When I worked at a retail place, I would have to sweep the place before closing and a crap load of other things (when other co-workers were just chatting) as well. It got to the point that i drempt I was sweeping and their were customers at the register I was running. I called out for help but no one came, then my bf at the time wakes me up saying I was shouting in my sleep for someone to "Please, someone come help me with sweeping!!"
