Maybe it's not all that hard to replace the glued-in batteries anyway. Seems every mall has two tiny mid-hallway shops that can do it.
When my sister's iPhone's screen broke, she took it to the Apple Store at the mall to use her Apple Care benefits. When they gave her some enormous time estimate, she marched to the iFixUrPhone stand and they did it in an hour. I believe Apple knows that this is a problem and is taking some preliminary steps to fix it. That's what this play is about.
I'm honestly surprised they even accepted you as a walk-in
Side note: I don't remember saying she was a walk-in. I don't know if she was; I'll have to ask her.
This is a truly terrifying thing to me about today's younger generations that have "always had" a device and have use the social platforms just as long. I don't mean for that to sound patronizing or belittling. It is just so out of my own experience it is hard for me to empathize, but I do sympathize as I realize that some of that dependancy was/is intentionally juiced by the social platforms.
