With more places asking for tips I often see "I only tip if I am sitting down". Why? Because it's what people are used to. In time, this too will be normalized and people will one day tip at these places too like they do at restaurants.
And frankly, people should be tipping at other places if they tip at restaurants since all the same principles apply - your plumbers, doctors, etc. work hard too, so they deserve the compensation the same way waiters do. And before anybody says that waiters make less (which is not true in certain states and Canada where they make minimum wage), then just remove the exception for minimum wage instead of having tipping. And no you shouldn't continue to tip in the interm because the servers themselves have no incentive to switch since they make more under tipping - they don't care about making minimum wage so why would customers worry about it for them? The usual response to this is that we shouldn't push people down but pull people up, so let's do that, tip everybody and pull up those compensation numbers.
