the simple answer is , because the dude that is flippin burgers doesn't have to deal with the self entitled person who is to cheap to pay the server that is serving him dinner ,,, your not liking doesn't change the fact that MILLIONS of people in this country ,including tipped servers , are trying to raise families on minimum wage,,,, hating on and not tipping servers is only spreading POVERTY... BECAUSE YOU HAVE FOUND A SELF -CENTERED REASON TO HATE THE PERSON LIVING WITHIN THE RULES AND TRYING TO MAKE AN HONEST LIVING AND ENTITLING THE RICH OWNERS TO LEAVE IT THE WAY IT IS... boycott the establishment that has tipped servers,,, don't ask someone to work for you for free , when they don't really have the right to refuse you service,,,,,, if you want it to change ... MAKE THE OWNER CHANGE... AND IF your just cheap ,,,,,mickey D'S IS STILL OVER YONDER,,,bottom line BY NOT TIPPING ,for WHATEVER reason ... the only thing you hurt is your SERVER and your SERVICE
