Tipping Handlers

[aviation1st]

So I travel out of the country on trips every so often and I know that most pilots tip their handlers to help everything go smoothly. What is your opinion on how much to tip? Does it matter depending on the region? I mainly travel to The Carribean and South America. Does it depend on what size aircraft you are flying? Do you tip right away or at the end of service? Any advice would be great. Basically - whats the standard?

I flew in that region (BVI, PR etc.) in 2002-2003. As I recall, 10-15USD was the norm back then.

Certainly helps with getting a good lunch when converted to Eastern Caribbean dollars;) .
