Most service workers get tipped 10%, and as the people in these services make the minimum wage - which is not enough to live on - you can be sure they need the money. In restaurants the service charge is usually included in the bill and is mandatory; when it is not included in the bill, it's customary to leave a 10% tip. If a waiter is friendly and helpful, you can give more.

There are many other places where tipping is not customary but is a welcome gesture. The people at local juice stands, bars, coffee corners, and street and beach vendors are all tipped on occasion. Parking assistants receive no wages and are dependent on tips, usually the equivalent of about a dollar. Gas-station attendants, shoe shiners and barbers are also frequently tipped. Taxi drivers are not usually tipped, but it is common to round up the fare.
