For those who say that if we did away with tipping resturants would have to raise their prices I say malarky. All you need to do is look at the prices of chain resturants in Montana and compare the price that you would pay for the exact same meal not including tax at that resturant in ID, ND, SD, WY (I haven't been in CO, NM, or TX since the early 2000s and while I have been in
UT it was just in the SLC airport so the price we paid to eat at a chain there might have been higher just because airport prices so not sure on those states). It doesn't matter if you go to Applebees, Dennys, Golden Corral, IHOP, Olive Garden or Texas RoadHouse you pay the same price.
If you want to go a bit further out there is only a $1.50 range difference between the highest and the lowest price charged at this chain for their weekday lunch
https://www.huhot.com/ (sorry not in all states as they are expanding slowly but if you ever get the chance to go to one their food is awesome and some of the grill operators put on quite a show. At least at the one I go to and they even have a tip jar for the grill workers though they used to have a better one where you voted on different things like which is better downhill or cross country skiing or which of two movies that released around the same time you liked better plus if you tell them you have an allergy they not only clean the grill they block off the area around your food while it is cooking and use a seperate clean spatula on your food no I don't work there though my sister in law started out as a waitress there and is now the front of house daytime weekday manager (they also have a back of house manager and an overall manager working at the same time and yes it is a favorite place to eat we even have our usual tables).
To those who say that people won't tip if it is not expected well according to my sister in law who was raised in WY (she moved to MT because there were more places to work in the town where I live than that town she was living in and met my brother at the resturant they both worked at she as a server and he as a cook-his cooking is now reserved for family) and worked there as a waitress/server and worked in MT as a server as well she actually got higher tips in MT compared to what she was making in WY about the same time period so 1 year difference.
