Silly Work Complaints

Thinking about the other day that I came to work without black pants I was supposed to wear (I have a limited time to change between class and work, but I try my best.) and I was told that I would be written up if I wore them again.

And the day before some people were sitting around doing nothing, same supervisor saw this, and didn't even threaten them w that at all. It just makes me laugh because do you?? Rlly care abt one of these over the others?? I'm over here working hard and upset I have zero help but ya one of these things is more important to fix than the other...
