The countries I have visited that have the best service have usually been the ones where tipping is not expected. The only thing there needs to be to food service is they bring your food to your table and come to you if you get their attention. If they can't do that, it is just a shitty understaffed restaurant and you probably shouldn't go there.

I am really not a fan of food service in America because it can be super overbearing and unnecessary because people are trying to get tips from you. I don't really need to be asked how my day is or given a sickly smile. Just need to be able to order, receive food, and pay.

I am from the UK where we do have tipping but it tends to be a flat 10% pretty much everywhere. In London it is automatically added on to the bill in most places. Because of this, service isn't better or worse depending on tips but places with bad service you just learn never to go to. And if service is actually dreadful, you just take the service charge off the bill. There is very little incentive for a worker to change their level of service based on tips and IMO that is a good thing.

The ONLY reason tipping is a thing in the US is because it allows restaurants to shift the cost of their employees to customers (because they underpay their staff and the tips make it up to the minimum). Also because some servers make more than they probably would otherwise.
