Well this was a few years ago now, basically a part time job while I was at college. They were really bad, the store manager would have a certain number of hours they could have in the store on a given day, and if they ran over they’d just pay you less (hours were noted in pencil on a chart on the wall, so if they had went over the allocated hours they’d just start changing what you’d worked, e.g. if I worked 6 hours on Monday night I could go in the next day and see it had been changed to 3, etc).
They also had regional managers drive round the corner on random nights every so often and do pat-down searches of staff as they left the store at night.
Loads of dodgy stuff about their treatment of pregnant female employees as well. I hope they have improved, but they were total bellends back then.
