The flowers here are actually garland of money. It can consists of 100bht to 1000bht. The money is stapled together and given by customers to their favourite singers on stage. Some of this girls in the large joints are really beautiful but need money, time and pak wan to sian them. But most of these girls got rich thai sugar daddies liao. If I din remember wrongly the cafe takes a 30% cut of every garland of flowers hung on the girl's neck. Nevertheless some of them easily hit 30k bht a night.
