Hotel moron

Well lets see here, where to start.
First of all, I work at a hotel and see and talk to a lot of different people. Some are nice and will tip the housekeepers and breakfast hostess but there are some real ass holes and just pure morons out there. I had a guy come to check in to the hotel, we looked for his reservation and found it for the previous night, after saying that to him he responded says he knew it was for last night but decided to come the following night and didn't inform us. I informed him that the hotel was sold out for tonight. He was mad and asked us, and I quote,"what the hell?! don't you call someone who doesn't show up to check to see if it was a mistake?" I almost laughed in his face. Are you kidding me buddy? we are not going to call every single no-show reservation. That's bull shit and he knew and said we would be hearing from him. This is now 2 weeks later and nothing. fucking moron.
