Some very accurate comments in this thread.
To the comment about the monkeys in a zoo, well, experience that group of bars a few times, and maybe you will realize, YOU are the monkey in the zoo
They do yell and shout a lot, and as soon as you sit down and buy a drink, most go about ignoring you and chatting amongst themselves or screaming at other guys to sit and buy a drink. So who is the hunter and who is the hunted in there? That section is on my list of least favorite bars to frequent. My buddie found a companion at one, but not so hot.
Rock star is a decent description. As long as you are in some areas throwing money around you are popular. Then have your money run out, you are a leper. It's too easy for most of us to be confused and think they really love us.
