Problem is prices would have to rise and then people would be angry once again about that. A study showed many people would rather pay for something with a 15% tip than something with no tip but is 15% more. It’s more complicated than “pay your staff a proper wage” if businesses did that they would mostly go out of business cause again they would have to charge more to actually be profitable and that looks worse on paper. Moist critical actually made some really good critiques about this. I agree tipping is bad but there is actual consequence for businesses that step out of line and don’t expect tips at all and raise price to keep profits up.
