One time some crazy bitch walks into my work, orders a pizza then walks out. 15 minutes later she comes in and starts screaming that we stole money from her because she "dropped her money and she cant find it." She then demands that we give her 20 bucks and a free pizza. I tell her to leave, she goes on screaming incoherently then throws her coffee at me, misses by miles, and takes off out the door. Manager calls the cops and she ended up spending the night in jail. Its great to see an asshole customer getting what they deserve.
or I hide my anger in a way that makes them wonder if I'm just clueless or a huge bitch.
For instance, I worked at the Cheesecake Factory as a hostess at one point. Everyone would always say "can we get a booth?" and I'd just smile and say "well if everyone got a booth we'd have half an empty restaurant now wouldn't we? hahaha, *chuckle/smile*-- let's see what we can do, shall we?"
