I dont know the waiter but unless he was blatantly rude to the customer than he deserves a tip even if it's not 15%. He would have had to do one hell of a bad job to not get tipped at all. From my point of view, in America, you tip, even if it's not a big tip. Now Im not saying the guy should have yelled at him on the beach, Im just saying, Corgan didnt Tip and then got him fired too. And the words waiter and Surfboard does not equal "slacker". That is a very ignorant thing to say. Out here the restaurant and hotel industry is basically the only means of employment some people have out here. I work in construction.Hawaii is an Island chain, lots of people surf here including me and I'm no slacker. Dude, Corgan is a snob I'm sure is service wasnt that bad or he would have complained in the first place. I tip a waiter or waitress even if she or he wasnt very good, and Im not a millionaire. Why do you think BC's original guitarist and bassist passed up mega bucks to do the reunion? Cuz the dude is a dick. You know what though, I think he qualifies as a guitar hero, I can be unbiased about it. He can shred it up and he has his own style.
