The title of the article is "Waiters Say Diners Could Use Tips on Tipping," but from what I can tell, the waiters and managers could use some tips on mathematics.
Here's an excerpt:
Something doesn't add up here. These folks want everyone to tip the "acceptable" amount or presumably, choose not to dine out. However, when the simplest suggestion, increasing the meal amount so that the servers can benefit from a living wage, we're told that this would drive restaurants out-of-business.
One former waiter, Yakup Ulutas, is proposing restaurants change the system. Ulutas, a 36 year-old restaurant manager in Atlanta, founded a nonprofit organization, Fairtip.org, to persuade restaurants to implement an automatic 20 percent service fee on every check. He estimates 2,500 waiters have joined.
You'd be hard-pressed to find a server who wouldn't love to see his or her employer slap an automatic tip on to every check. But wouldn't it make more sense for restaurants to hike prices by 20 percent and raise workers' salaries?
"That wouldn't work," Yakup says. "Many restaurants wouldn't be able to afford to pay higher wages."
Again, presumably, it's only the non-tippers and low-tippers who would object to a built-in tip (or "autograt"), but that shouldn't matter, as servers and restaurant-owners must want these folks to stay home, anyway. (Unless they actually think they can tell people who don't believe in tipping x% where they ought to eat AND what to do with their money.)
The point is, either way, you're only left with patrons who believe in and support the tipping system. If the restaurant business can't survive without the folks who DON'T believe in the system, maybe the system should change to suit these people.
