How many bikinis do you prefer a girl to be wearing?
More practically, though ... it's probably not so much your morals, as it is the public nuisance caused by the patrons of these establishments. From the story, it appears that there's a gang problem associated with them.
Gangs will be gangs. If they're not out in the cafes, they're in the back with the illegal gambling operation.
Hello Grammer police.... lol one bikini will do lol
