I have been to this restaurant before, usually the food is normally good, but the service was very poor this time around. The waiter asked me for more tip because I didn't give "their" minimum amount even though I had paid for three people. I refused to give more tip and the manager came over to our table and insulted me for being "cheap". I'm sorry but a tip is a bonus and a personal donation for a service. If you desire a minimum tip for your employees, increase their salary.
