I'll use exit for example They started a new party this past saturday caled disco tech The whole reason exit did this was they were doing there saturday party for a 2 months with no promotions there numbers were around 2,000 to 2,500 The club wanted more money so they hired promoters to bring in more people this past saturday they did a little over 4,000 people it doesn't take a genius to see how promoters help a party now the club only keeps the list open from 11pm to 2am 1. not everyone comes in on a list and 2. after the list closes everyone pays full price and the promoters make no money so it is in the clubs best intrest to pay there promoters or they will lose the crowd the gained from promotions
