Check your bill before tipping
Many restaurants, hotels, and other establishments in the U.K. (England, Ireland, Scotland and Wales), Chile, Brazil, Portugal, and many other countries already add a service charge. “An exception is Dubai—where the added service fee usually goes to the owners, rather than your server. Be sure to personally hand the server an additional tip in this case,” says Glenn. And check whether the bill specifies a service “charge,” as opposed to service “tax,” before thinking you’ve been charged the tip. A “tax” does not go to the servers. One note on Brazil: “Tipping is really not required even though they would like it due to small wages,” says Boland. Of course in tourist spots, the workers have become accustomed to Canadians giving small amounts.
These are the strange travel faux pas any globetrotter would do best to avoid.
