New Found Bitch-i-ness

So, Today I realized that I have this "New found sense of Bitchiness". I can be a real bitch if you get on the wrong side. I never knew I had it in me. Earlier at work a guest came to ask for some extra sheets...so she comes and asks for 4 sets of extra sheets. So now I'm like.."How many people are in your room. She says 3 adults 1 child. I check her reservation and it says 2 adults 1 child. I tell her that there is nothing i can do for her right now....she has to wait until the morning when housekeeping is in. ....I am not Housekeeping. ...She needs to pay the fee for the extra person -$30. She starts ranting and raving about how she is going to complain to the manager ..blah blah blah....shes still looking at me like where are her sheets? I am the manager at this time, so she can complain all she wants she's still gonna end up paying extra and not get any sheets anyway!
