I could see them putting a “Minimum Wage Hike Surcharge” on the checks. Wanna bet the diners are not at all sympathetic, that tips would dive?
I believe that some restaurant(s) did that, and were forced to retract that policy when the news outlets picked it up and claimed it was “illegal” or something.
Some places outside the U.S. do not have the custom of tipping. Take Australia, for example. In Oz, there is no “tipping”. A “tip” is something you give a homeless person or a beggar. It’s considered something of an insult, as if you consider the person pitiable and in need of your benevolence.
Then again, if I ever get the chance to do so, I would deliberately tip certain individuals a few coins if I were ever forced to meet them to show them exactly what I think of them. Nan Pelosi, Obama, Reid, Sharpton, Jakson, Holder... just to name a few.
