So I didn't follow it back to the souce. Doesnt matter. I shouldnt bother replying to you because you are simply wanting to be an asshat who has a gotcha. You people suck, no intellectual desires at all.
I will die on this hill. I have seen restaurants try and fail. I have known and worked with enough people that hate this idea. The don't want their wages cut, and they know it will.
UNLESS: These two always come up, and its reasonable: profit sharing or commissions. People are nervous about profit sharing (its the food biz after all) and comissions are just tips with extra steps.
And me personally? I think everyone should earn the same: an hour work is the same no matter who you are, so its not like I want tipping.
But your silly ass "gotcha" aside, I will concede that there is a lot of pressure to keep status quo. I have worked with restaurant owners and told them: show your staff how much money you are making everynight. They are doing the work, make them see what they are getting out of it. Restaurants budgets are tight.
