Yes there are bitchy crew around, but then that is the same in ANY job- there will always be at least one person you don't get along with. We have all been hired because of our people skills,we should make the most of them and either try to get along or ignore the bitchiness.
Sure there will be comments but we can CHOOSE how we react to them. As said, see the funny side, have a laugh with your friends later on, and so forth. As Elanor Roosevelt said "No one can make you feel inferior without your consent"
