Dont worry man, I didnt care for the $6 I'd get from those 8 hens pecking at their coffee until 3:30 in the afternoon. There are limits. You're probably naive, so I get your attitude, but smart restaurant owners discourage these types from even coming into the establishment at all. Much like they dont want a 400 pound fattie wearing a path from his table to the all you can eat buffet for 4 hours (I've seen it, dude got seconds about 9 times). Oh, by the way, Fangio avatar? Argentine are you? Among the shittiest tippers in the solar system.
