Yob Culture

Another example of anti-social behaviour in today's world, more specifically, my part of the world:

My youngest son and I went to do some shopping at our local Tesco. When we were leaving, a young man was standing in the entrance shouting "Bitch!" at one of the girls working a till. He looked like he was ready to pounce, the way a boxer does while waiting to throw a punch, so I got Jack out of there as quickly as possible.

From where I was putting the shopping into the boot of my car, I could hear how the guy wanted to buy a case of beer, but he didn't have any ID on him to prove he was over 18. He looked about the same age as my daughter -- 16 -- so that didn't surprise me. One of his friends did have some ID, and the cashier was happy to sell that guy the beer.

That wasn't good enough for the yob. He had to scream profanities and make threats until a police officer was able to get him to leave. As he walked away with his friends, he continued to yell at the store, at the police, at the world in general.

What makes people do things like that?
