I've worked in restaurants and retail but never a job where I relied wholly on tips (even pizza delivery has a better per hour than serving), but in the kitchen you often do even worse than servers. I still feel like I'm reasonably empathetic to the situation though.
I generally have 2 settings for tipping, either 18-25%, for a good job, with the difference between good and above and beyond in some way (I notice my water always being full, extra helpful/funny, etc). Then, very rarely, but only if deserving, I leave no tip. If a server is an asshole or goes above and beyond to make me feel like my table not important, I return the favor.
