Uber passengers in Canada may soon find themselves facing a classic service industry conundrum: "How much should I tip?"
In an announcement to U.S. Uber drivers on Tuesday, the ride-hailing service said it will roll out a tipping function for its app in all U.S. cities by the end of July. The tipping option is already online in Seattle, Minneapolis and Houston, Uber said.
The ability to tip Uber drivers through the Uber app is likely coming to Canada by the end of the year, suggested Uber Canada spokesperson Susie Heath.
