I am however saying I don't really feel sorry for someone in the industry being "treated this way" since it's something Rachel should be expecting.

You keep saying this, but I don't buy it. So what, because I used to work in customer service, I should have expected to be cursed at and have things thrown at me? Because yes, it's a part of the job, an unpleasant one, but I still have the right to be upset and angry over it. And just because it happened semi-often doesn't I went through my day always expecting it to happen, like you seem to be implying every actress or actor should about getting fired... That excuse does not fly, sorry. You're entitled to your opinions, but don't expect everyone to just agree with you because you say so...
