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 Apple 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.
The move puts a spotlight on what can be a sensitive topic for customers, workers and even Starbucks, which has faced lawsuits over how it divvies up the contents of tip jars among workers. Some customers are happy to tip for friendly service, knowing that baristas don't earn that much. Others say that they already fork over enough money and shouldn't be made to feel like they should throw money into a tip jar as well.
Zee Lemke, who has worked as a Starbucks barista in Wisconsin for more than three years, said most customers nevertheless leave a tip of some sort. She said tips generally add between $1.50 and $2 to her hourly pay of $9.05. But she noted that there's no rule on how much baristas can expect to earn from tips.

"It varies a lot from store to store, even in the same city," Lemke noted. Since she works at a drive-thru location, for instance, she noted that tips go down when it's cold out and people are less likely to reach out to put money in the secured tip box that hangs off a ledge.
