While Americans are questioning if there are any places left they aren't expected to tip at, those in other countries are watching with confusion.
"Most establishments will add a discretionary charge automatically," Laura Windsor, founder of an etiquette academy in the U.K., told CNBC Make It.
If such a charge appears on your bill, there's no need to tip, although it's always an option.
If a tip isn't automatically added, customers usually leave an extra 10-20% of the total bill for workers, Windsor said.
But there are some circumstances in which Brits would never tip but Americans always would, Bryant pointed out.
