The only time I got hit badly for a bribe was at the Caracas airport in Venezuela.
It was blatant. Systematic. Though I pride myself on avoiding these encounters, I paid up that time — US$12 or so I could make a connection. Irked was I, but happily I bumped into a friend and we spent the last of his Venezuelan money in the bar.
Other times I have paid baksheesh, of course, but it was part of the normal course of business in those countries.
We “negotiated” a Park pass in Peru I recall. It was a fee that gringos normally did not pay.
In any case, Haiti is the bottom of the barrel. Finland the least corrupt.
