Yeah, I love hearing that. As an Ugly American though I never even try. If they want my money, they can say it in English, god knows every time CNN turns on a camera over there you have piles of people speaking English. But I'm a huge, HUGE (like 40 years around the service industry) believer in tips. I tip well, and tip at the start and frequently after that. Funny, their language skills get much, much better.
