(NBC NEWS) -- For as long as there's been ham and cheese on rye, there's been a tip for the server who serves it. Lizzie Post, of the Emily Post Institute, says tips are still needed.
"The servers aren't actually paid a minimum wage. They're paid less than that, and that's why in America, that we tip" states Post.
Restaurants can legally pay waiters and waitresses as low as two dollar and 13 cents an hour. Tips act as an incentive for the server to serve well.
The has IRS announced that starting next January, they'll be changing the way tips are taxed. Sparking the debate over tipping in general.
"I think it's going to be really interesting to see how it pans out in the U.S. If we move to more of that European system" says Post.
There's still no tipping in that European system. The cost of the service is factored into the price on the menu.
But Post, who was once a waitress herself, says eliminating tips could eliminate the incentive.
"I work hard to make sure I'm always getting above a 20% tip, as many times as I possible can. I can earn more, if you don't put a set limit on it" says Post.
A sentiment shared by so many servers, that few expect tipping to disappear anytime soon.
