Need a Fixer Upper Doc!

Zyta thought that her boss should really decide to choose a specialization for his store. At the moment the place basically did almost anything related to technology and machines. They sold electronics, both new and old, performed customization and maintenance and sometimes the boss would even build cyborg parts through commission. Zyta was pretty much an all-rounder when it came to any kinds of machines, but sometimes it made her anxious to try and describe to customers what exactly they did here. She didn't get this job to perform customer service.
And yet Zyta was manning the front desk, while her boss was at home sick.

Zyta sat anxiously the the chair behind the desk, glancing at the door and praying no one would come in. She was in the middle of doing some small fixes to a blender, it's motor started smoking after only 10 seconds of continuous use and Zyta knew where the problem was. One slightly loose screw could mess up a lot of things. So Zyta had opened the blender up and was now in the middle of re-arranging the motor parts. Seriously, who came up with such an inefficient design?
But she almost punched a hole on the thing with her screwdriver, when the shop doors were suddenly swung open. Zyta looked up, her eyes wide, and looked at the...person? who had just come in.

Zyta stared at the woman, who had more machine parts than organic. Zyta had been around long enough to have seen cyborgs, but this person was unlike anything Zyta had ever seen. They were like a strange mix of a fighter jet, eagle and a person.
Wait, repairs and a tune up?
Zyta stood up, leaving the blender alone for now, and nodded a bit to the customer. Since apparently that was what she was.
"Um, do you have an appointment set up, or something? Because bo-, I mean, the owner is out today."

"Uh, no, I mean, I don't think so..."
Zyta hadn't still fully grasped how her boss handled customers, but he had taken in many customers who just walked in without a reservation. And then there were some people who called in beforehand and reserved a certain time and date. This person wasn't one of the regulars, nor had she come to the shop while Zyta had worked there. Zyta would've definitely remembered this marvel of engineering.

The woman took her time observing the shop, and Zyta took her time looking over her body. Well, the mechanic parts. Zyta was almost drooling from all the high-quality tech used on the wings and legs, and honestly she wanted to get her hands on them. Zyta wanted to see what kind of hydraulics were at work on those wings, and she wanted to see if the mechanic parts had any kind of mechanic frame or if it was still organic. Though that would've been bad engineering, those kinds of limbs would be best supported by artificial steel bones.

Zyta was snapped out from her engineer's daydream, when the woman spoke again, and Zyta forced her eyes to look into the woman's eyes.
"What? Oh, you don't need to. I can, uh, take you in now."
What was Zyta talking about? She couldn't take a customer that was supposed to go to boss. But...she really wanted to see how this woman worked. And boss had taught Zyta a lot about working with cyborg parts, she could do the kind of tune up the woman wanted and if she couldn't she'd just ask the woman to come in later when boss was around.
"There's a backroom workshop for maintenance, follow me."
With that Zyta moved over to a wide doorway covered by a curtain, that lead to the back of the shop.

This person really was cheery. With a just a bit uncomfortable expression Zyta held the door open for her, people who were too happy or cheery or smiled a lot made her uncomfortable. And a bit annoyed if given time. This person wasn't annoying her yet, and Zyta hoped she wouldn't start annoying her during the maintenance. That could affect her work.

The workshop was a large area at the back of the building the shop was in, it had enough space for Tengu to spread her wings some if she wanted. Thankfully most of the equipment was made of steel, so it wouldn't burn Zyta immediately if she touched it. The room also had a desk with a computer in one corner, a kind of like a hospital table on one side but a lot sturdier, looking like it could hold a rhino. And it probably would. And the walls were lined with all sorts of tools, and Zyta knew how to use each and every one of them. Her boss had taught her ever since she came to the shop few months ago, and Zyta was a fast learner.

The woman kept chatting with Zyta after she had taken in the workshop, and Zyta had gone to the computer and opened a new customer file, where she could write down what kind of maintenance she did on Tengu if the woman ever came back and Zyta or boss needed to look up her info. Zyta put the name Tengu as the headline, and then turned to speak to Tengu.
"I'm Zyta. You don't need to detach anything yet, or be strapped down. Unless you're planning on wreaking havoc."
Zyta wasn't joking, she said it all with a serious face.
"Just sit down on that table. Uh, please."
Zyta gestured to the sturdy maintenance table, more than big enough for Tengu to sit there comfortably.

Zyta pulled on her work gloves, that covered her whole arm. In case Tengu had iron parts.
"Now, can you say again what was the issue with your mechanic parts? And tell me beforehand if you have iron parts, I am part fae and iron burns me. Uh, please."
Zyta always forgot to add the please. She sat on a stool that had wheels and rolled over to Tengu, propping a pair of welding goggled on her forehead in case she needed to use the blowtorch. You never knew.

Now Tengu was talking to her...conscience, perhaps that was the person's internal computer or such, implanted in her. Or else Zyta was just giving maintenance to a mentally unstable, perhaps even sick individual. Because being weird had limits. Well, Tengu wasn't aggressive or in any way make Zyta feel threatened, so she just waited for the consicence to be done listing the malfunctions.

Eventually Tengu began explaining, since the consciemce was only in her head, and it was Zyta's turn to nod and let out few affirming sounds now and then. Yes, all of these issues sounded like something she should be able to help with. As for the materials the woman was made with...
"Impure iron has little to no effects on me."
Zyta stated, and then took a moment to take a look at Tengu again, quietly appreciating the machinery. Tengu herself seemed to have minimal knowledge of her own systems, which baffled Zyta. Perhaps they were forced on her? That wasn't a nice thought.
"I will start with the smaller malfunctions, your toe and antenna, and move on to your left wing from there. Feel free to talk to me or ask questions during the maintenance, I am not easily disturbed, and I will answer to my best capabilities."
Like Zyta's boss said, being a personal mechanic was similar to a hairdresser, chatting was part of the job. Zyta hated it, but the actual fixing part of the job she loved.

Zyta rolled closer, and pulled another smaller table with her, and locked its wheels.
"Lift your left leg on the tablebn. Please."
