Are you made of money? Most people don't or can't afford to quit a job just because their bosses are stupid
Doubly so for the intern, whom it it is her first experience
That's an excuse, if she can't find a job literally ANYWHERE else, I call it a skill issue
That and there's a thing with some people being way too spineless to actually quit, so they just take whatever abuse that goes their way, those people have no sympathy from me
Some jobs just aren't worth it no matter how you slice it
