Working at a job that you hate is the pits, especially when you were so excited about it. If this woman continues to yell at you, let 'er yell. If she is downright abusive, that's another story but sometimes people are just mouth-o-matics and it's directed at other people but it's really that they're yelling at themselves. In the grand scheme of things, she's but a blip on the radar screen. She probably hates her job even more than you hate yours except that you're in the catbird seat because you won't be doing this forever. She probably will be. Flick her off your shoulder like the little gnat that she is and say "NEXT!". (To yourself, of course. )
