So I'm an a-hole and other Christmas cheer

The other day I was at work. I work retail and work in the cash department of the store. I was blocking the line for a cashier so she could go to lunch and this guy walks up and I tell him that I am sorry but I am closing this line so my cashier can have lunch. He looks at me and calls me an "asshole". The guy behind me says 'Wow! He is full of Christmas cheer." To which I replied "That is not all he is full of". I am amazed everyday at how insensitive people are. Just because people work in a retail environment does not make you any better. The last time I worked in retail at Christmas, at the very same store mind you, this guy was angry when I told him about the lines and that we had all the people working we could and he tells me "Do you know what my time is worth?" To which I reply "No sir I do not, but that does not change the fact that the lines are what they are." Seriously, it is no wonder why I really cannot stand people during the holidays. I understand that people don't want to wait and we are a society of instant gratification, but it makes me think. If you are this big of a jerk to strangers what are you like at home. I have to apply the plastic smile and be cheery towards people. I get paid to do that. I get paid to try and smooth out angry customers. It is to a certain extent my job to take some abuse away from cashiers. I get it, and I am pretty damn good at what I do. People have told managers how good I am. Recently the store manager took a call from a customer who wanted to compliment me. That was nice, but for every one of those there are 20 other people I would rather grab by the belt and collar and toss though the doors. I don't do it I am just very tempted to. I'm just sayin'.
