I started my new job yesterday.

So I started training at a new job yesterday. It’s not fast food but it’s a quick service restaurant. I was taught all of the basics and cleaning. But I spent most of my time cleaning than learning how to handle the cash register. I’m 17 and this is my first job so I don’t know how training works. The person who was training me was helpful but I feel like he was kind of annoyed because I kept asking him a lot of questions and stuff. I was suppose to get out at 11 but they kept me there until 11:45 to clean the entire floor and mop. Was that fine? I ended up getting home at 12. And I heard that here in Texas they can’t keep you past certain hours. I’m so tired and my feet hurt and my back. I have to go back in today and close at 11. They didn’t tell me anything about having breaks and I’m not used to being on my feet for such a long time
