No one ever said to tip 20% regardless of the level of service.
I'm pretty sure you did like 4 posts before this one. You were hella butthurt over the concept of tipping someone 15%. You were taught 20% was the standard and then it just applies to everyone else in the world. I used to work in a tipping industry and the only worse than a bad tipper are servers who bitch about tips. These people don't
have to leave you any money, whether it's socially acceptable or not there are no true rules. This fact alone should make people gracious when they get anything at all. Sure it sucks to work your ass off and not get tipped like you would expect but there really IS a 'get over it.'
I used to work in coffee where the standard isn't even a percentage, it's a dollar. One dollar. You could order a 30 dollar order with five drinks, a toasted bagel with the cream cheese spread on it because they are too lazy AND a custom made sandwich, people will still just tip you a dollar. It's still a free dollar for doing my job. I know that serving is hard work, very fast-paced, stressful, adaptive... Nonetheless I have done harder work in industries that don't tip me. Tips are nice but you can't let them spoil you or ruin your day.
Just because people SHOULD do things doesn't mean they will, quit getting your panties in a twist over it. There's a lot of things people SHOULD do - have you ever driven a car? Do people EVER do what they're supposed to do, like pay attention to other people on the road?
In my opinion, it's really easy to read a customer from the very first interaction and see if they are worth that extra mile you want to go to get a nice tip. If you don't, then learn from the experience. Getting upset over it doesn't help anyone. Some overzealous jaded server bitching about how you should give them more free money is not exactly a convincing reason. Each one of your posts I read made me want to tip servers less and less.

My serving pet peeve is a server who won't ever refill my water glass.
I agree that an on point server deserves more than 15% tip, anybody who has served people understands that. Your approach is all wrong, though. You are far too expectant. Expecting people to go above and beyond just leads to disappointment. I really do understand getting frustrated over it but that's when I realize you have the wrong attitude about the whole thing.
