Starbucks will soon let customers leave tips with its mobile payment app, which begs the question - how often do people tip their baristas?
The coffee chain says the mobile tipping option, which it announced more than a year ago, will be available on its updated app for iPhones starting March 19. The rollout comes as the company's app has surged in popularity, with roughly one out of every 10 purchases now made with a mobile device.
After paying with the app, Starbucks says customers will be able to leave a tip of 50 cents, $1 or $2 anytime within two hours of the transaction. The tipping option will only be available at the 7,000 of the roughly 11,000 Starbucks locations in the U.S. that are owned by the company.
