Cell phones didn’t kill it, VIP sections did. Sections used to be a small part of the club. Reserved for real ballers and friends of the owner/promoter/DJ. Nowadays, clubs can be 80% VIP sections with the remaining 20% being corridors basically. Not uncommon to have no real dance floor in a modern club. Capitalism is to blame here.
The drive to get every little penny from partygoers has led to the opening of a new market of spots that are anti-everything the big clubs stand for. I’ve noticed more loungey type spots and even damn near dive bar type spots popping more of late. A large percentage of people don’t want to break bank (or get treated like a plebeian without a table) just to have a good time.
