In Mexico, it is customary to tip 10 percent in restaurants, and you may also give a couple of dollars to any passing band whose playing is particularly pleasing. However, the American custom of tipping 15 to 20 percent is practiced at international resorts, including those in Los Cabos.
Housemaids in hotels may be covered by an all-inclusive charge, but welcome US$2-$3 tips per night, and don't forget to hand over something small to the little boy who runs to clean your windshield or who fills your car up with gasoline for you. Mexicans always tell you that tipping is not expected; it may, however, be well deserved and they always thank you.
