I think it would be cool if I could express my personal beliefs at work by refusing to serve certain groups of people. I'd start with smokers and adults who don't wash their asses properly. Then people who don't understand English, and people who don't pick up after their children. Anyone who returns my calls without first listening to the voicemail I left would also be out. Neck tattoos? Sorry. Those weird cleavage piercings maybe. I'd have to pray about that one. People who can't hear very well and refuse to wear hearing aids are out. Now that I think about, I would love to just lock the doors and play on the internet all day because I believe deep down that humanity is a scourge. 

It's a good thing I'm a professional that takes my job seriously.
