Tipping is a common practice in Dubai, but it is not required. In restaurants, usually a 10% service charge is included, you can also tip waiters directly, especially if this is not included. Taxi drivers do not require tips, but you should round up to the nearest dirham on the fare. You are advised to tip a couple of dirhams to bellmen, baghandlers, supermarket baggers, and windscreen washers at gas stations.
