Quick, serve me a drink

I had a long and stressful afternoon today. It was like all the "crazies" were out shopping. And they came with an attitude too. I wonder sometimes if some people really don't have common sence? For instance, when you're paying for an item you're buying and you are told it comes with a warranty, does it make sence to ask "when does the warranty start?". Duh!! And the funniest thing is that of all the people I work with I am the most patient and accomodating, and the "carazies" had me stressing today. I think everyone walked out of Macy's and went straight down 7th looking for a bar.
