I did it!
I asked for stool when cashiering but I was told that it wouldn't be possible, so I asked if I could bring water in to keep my hydrated as I get hot very easily.
I'm a little bummed about not being able to have a stool or chair but I'll do the best I can, I guess. And even though the hours range from 15-20 per week, I can do as little or as much as I want, so I'm going to work twelve hours and leave it at that.
For those who have not worked in a while and returned to work, did you find the adjustment hard?
I know this is going to affect my SSI but I don't care since I don't get much from it to begin with.
