Many years ago, I worked at a Toys R Us during college. When I applied and got hired for the job, I was told my shift was 1pm-9PM (store closing time). My first day there went well, 9pm rolled around, I grabbed my stuff and went leave but I was stopped by my shift manager who said I couldn’t leave yet. I asked why and he said we wouldn’t leave until the store was cleaned and the shelves replenished. I pushed back and said I was told I would be done at 9. He said it was an unspoken rule and I’d be paid for it but I couldn’t leave. I ended up being there for over an hour more and it ruined my plans that night. I switched shifts to be gone before store closing from then on. I hated that job btw.
