But the restaurant is not a nightclub, the number of trouble, but the severity is not the same. If there is a problem in a restaurant, you can call the police. Nightclubs are best dealt with on their own.
Because the degree is different. Restaurants are drinking too much, if the security guards to drive away, easy to get into trouble, because you do not have the power of law enforcement. Trouble quite a lot.
Nightclubs ...... can't say that online. But in comparison, a doorman or chef waiter at a restaurant can be dealt with simply. Any young man can be dealt with.
Restaurants are mostly just trouble with alcohol. For example, hitting someone with a bottle is never an empty bottle because it's all drunk before hitting someone.
So when you get in trouble, you either call the police or the owner. There must be guys in the kitchen, and they're all fat, so surely they can fix it.
