1,000,000% agree! I was just talking with my dad about this. Neither of us actively drink and we had dinner at Gibson's in Rosemont, IL last week. We didn't order alcohol, but the server was fantastic throughout. We didn't even order steaks (it's a steakhouse) and the guy was amazing. I tipped him accordingly because my service shouldn't depend on anything that I order. If I get a hamburger or the Australian lobster, my service should be about the same.
