The NYT, in an article whose premise is too ridiculous to summarize (I'll try: Filipinos get really violent about their karaoke songs):
But in karaoke bars where one song costs 5 pesos, or a tenth of a dollar, strangers often rub shoulders, sometimes uneasily. A subset of karaoke bars with G.R.O.’s — short for guest relations officers, a euphemism for female prostitutes — often employ gay men, who are seen as neutral, to defuse the undercurrent of tension among the male patrons. Since the gay men are not considered rivals for the women’s attention — or rivals in singing, which karaoke machines score and rank — they can use humor to forestall macho face-offs among the patrons.
In one such bar in Quezon City, next to Manila, patrons sing karaoke at tables on the first floor and can accompany a G.R.O. upstairs. Fights often break out when customers at one table look at another table “the wrong way,” said Mark Lanada, 20, the manager.
“That’s the biggest source of tension,” Mr. Lanada said. “That’s why every place like this has a gay man like me.”
