The BBC reports:
A bar in eastern China has come up with a novel way of attracting clients—they are allowed to beat up the staff.
The Rising Sun Anger Release Bar in Nanjing lets customers smash glasses, rant and even hit specially trained workers, state media reported.
The owner, Wu Gong, told China Daily that he was inspired to open the bar by his experiences as a migrant worker.
Because he got so frustrated he just wanted to hit people, or because his employers kept hitting him? The article doesn't say.
According to Reuters, "most of the patrons have been women, especially those working in karaoke bars and massage parlors." Presumably, after a long day of getting beaten up by masseuses, the bar's employees can visit those parlors for a nice, relaxing massage.
Obligatory pop culture reference:
MAN: Look! I came here for an argument.
MR. BARNARD: (calmly) Oh! I'm sorry, this is abuse.
MAN: Oh I see, that explains it.
MR. BARNARD: No, you want room 12A next door.
