Tipping is part of the culture of Mexican economy. Mexicans working in service industries earn modest wages and rely upon tips to supplement their weekly take-home pay.
In restaurants, there may be a service charge of 10 percent in which case tipping isn’t obligatory. For exceptional service, 20 percent is sometimes given. It’s best to tip in cash so the waiting staff benefit.
In bars, it’s usual to tip 10-20 Pesos ($0.78-1.57) per drink, or 15 percent at the end of the evening if you run up a tab.
Every service provider hopes for a tip – hotel staff, hairdressers, people who guard your car, people who bag your shopping, massage therapists – from a few Pesos to 20 percent.
Taxi drivers don’t expect a tip but many people reward them for loading and unloading luggage with a tip of by rounding up the fare.
