The Dutch government requires that all taxes and service charges be included in the published prices of hotels, restaurants, cafes, discos, nightclubs, beauty/barbershops, and sightseeing companies.
Even taxi fare includes taxes and a standard 15% tip. To be absolutely sure in a restaurant, for example, that tax and service are included, look for the words inclusief BTW en service (BTW is the abbreviation for the Dutch words that mean value-added tax)-or ask. The Dutch are so accustomed to having these charges included that many restaurants have stopped spelling it out.
Dutch waitpersons appreciate tips and rely on them to supplement their salary. To tip as the Dutch do, leave any small change up to the next euro in a cafe or snack bar; in a restaurant, leave up to the next 5 euro or more if you think the service was particularly good. .
