Tipping in foreign countries
How do you figure what to tip (if at all), who to tip, and how much when traveling abroad? Is it something you actually take the time to research or just kind of figure out on the fly?
It isn't something I even think about before I go abroad, but have made a few embarrassing mistakes over the years (i.e. trying to tip a taxi driver in Singapore). Still something I am often confused about (esp. in global hotel brands abroad).
