One of the things I really have a big problem with is the fact that certain people take personal calls at work and stay on the phone for an hour - fighting with their husband, children, etc. Some people take five or ten minutes to talk and then hang up. Others do not. It bothers the hell out of me.
Also, when you're doing your personal call bit, there is no reason to be rude to me when I'm trying to find a specimen that has been received. I have the damn sticker. Just let me look at what you have sitting in front of you so I can get my specimen. It is important. Okay? Honestly.
Next time someone asks me to cover receiving when I'm busy, a big N-O will follow.
