I’ve said before, the people who work in restaurants ain’t going to be wild about this for two reasons. First, people will tip less because they know the server is getting increased hourly wages and the price of their meals is going up - are you going to give 20 percent when the meal goes from $ 15 to $ 20 as a result? Second, the wages paid are reportable income to the IRS by the restaurant owner - in the “old” days, when the employees made $ 5 or whatever an hour, they didn’t report much more than this, i.e., IRS always assumed there was a lot of unreported income from servers consisting of tips. Now, with tips going down and reported wages going up, they will probably lose whatever they get in increased pay through increased taxes.
If I knew my server was being paid $15 an hour, I would not tip.
