A tip of 10 percent is generally expected in higher-end restaurants and hotels; however, in these types of establishments, you may find a service charge added to your bill, in which case it's unnecessary—though appreciated—to tip extra. You should also tip your tour guide, though the amount depends on the length, type of tour, and service (for example, a multi-day tour has a typical tipping rate of 30 to 50 soles a day, whereas it's acceptable to tip 5 soles for a two-hour tour). On the other hand, it is uncommon to tip taxi drivers and staff in small family-run restaurants.
