How do you handle a drunk customer

Tweet

I usually work at a restaurant during the weekend. Today, there was a customer coming in sitting at the bar. obviously, he was a little bit of drunk, but we still have to serve him with food and beer. He was flirting with the waitresses, and also crazy - talk to other customers. I was suppose to keep him company, and distracted him to harass other customers. I just do my best to keep him busy until he finished his meal and beer. Luckily, he didn't make a big scene, and I just escort him out of the door. He left some tips for my kind service, and I appreciate him too. What would you do when you encounter a drunk customer?
