I have two friends with whom I will no longer travel simply because they not only hate to tip, they virtually do not. Recently, while visiting casino buffets, John got all over me for leaving a tip. "Nobody tips at a buffet," he sternly admonished, "because you're NOT supposed to!" We had quite the discussion, but he just disgustedly shook his head. BTW, I don't believe he tips in restaurants when he picks up the tab. Don will leave tips in restaurants, but 10% would be pushing it. He will tip a buck for a drink in a casino IF I remind him and call him a cheap a$$. But the straw that broke the camel's back with me was when he said that if I left a tip for housekeeping, he would take it. "They have jobs, if they don't like the pay, they need to get a better job!" There was no reasoning with him. BTW, I did leave a tip, he didn't take it, but I've never heard the end of how I "Throw Money Around!" How would you react to these situations? Me: I guess I'm just passive aggressive. I tell them why I tip, why they should, then shut up. It will be a cold day in Hades before I go with either to Vegas again.
