And it certainly is a maxim that you charge what the market will bear.
But there is an internal problem with approaching it with the thought, "I'm gonna soak 'em for every penny I can get." The latter is a dark side of capitalism and a basic flaw in people that will coarsen society as it becomes customary.
There may not be a "just" or "fair" price, but there is a moral price.
I don't believe that owners can morally (without some guilt lurking in their hearts) justify raising their prepared food prices because the customers weren't tipping; that part of customer contributed wage they weren't paying was going into their pockets, not keeping the food prices down.
My observations.
So you believe the business owner can not morally raise prices to make up for higher wages? Is that your position?
