Why do people like crowded noisy bars so much?

My friend took me to a popular dive on saturday. I told him I didn't mind, but I really did. I like that bar on weeknights but saturday night there was a HORRIBLE experience. We had to push and shove our way through the crowd, wait forever to get the bartender's attention, suffocate on the smoking patio, there was no place to sit, the music was too loud, the crowd roar was louder. You can't talk to the person next to you without shouting and you can't talk to the person across the table from you at all. There was nothing to do but people-watch and drink. What is the point of spending $6 on a beer if I can't even enjoy it? The place was packed, so they must have been enjoying themselves, but I was bored out of my mind. I don't see the appeal. Someone please enlighten me.
