A soldier or sailor is the definition of the customer the club does not want: he does not have a lot of money to waste, he travels in a large pack of similar men, he and his friends are not afraid of the bouncers and are always prepared for a fight.
The dream male customer for a club owner is a single guy or a guy accompanied by at most one or two friends who is in his thirties, has plenty of discretionary income to spend on sending overpriced bottles of champagne to a table of women, and who is scared to death of his bouncers and will therefore not cause any trouble or fights.
A few years ago, while visiting NYC, I went to one of the fancy clubs in the Meatpacking District with my wife and three of her female friends. They're all quite attractive and were wearing their best going-out outfits. We were about to get in line, but one of the bouncers waved us to the front. A group of 5 meathead guys standing standing near the front started complaining they'd been waiting forever- the bouncer suggested that they bring some women with them next time.
That'a just how it works- young, single guys in large groups aren't really what clubs or bars are looking for.
