I hate tips

I feel that the service in USA is one of the worst I have receive ever and people are expecting at least 15% but lately, even McDonald ask for it. I also notice they ask apart of service included extra tips, like 5%, 20,60 even 100% if you are drunk or distracted might end up being the service higher than the food itself

I understand most of servers earn the minimum but why don't they get paid better and we pay for same price service included

It's getting out of control
