What is the rule for tipping?
Restaurants: When you get your bill for the meal you should see a Service Charge of about 10-12% at the bottom. This is the gratuity/tip that is divided up between ALL restaurant staff, not just your server. If the Service Charge is already added to the bill there is no need to leave more money unless you fee that the service was exceptional and that the server went over and above normal services. If this is the case, depending on the cost of the meal, an additional 5-10% can be left on the table for the server or given to them by hand directly.
