I've had people try to scam me in Italy but that never worked, drivers demanding extra money for putting your luggage in the trunk should be dealt with appropriately (though that one never happened to me, it would seem that 20 euros is a bit excessive), Costa Rica and Morocco I have no experience with (though I'd expect Costa Rica to be more or less like Panama and I didn't have any issues there on multiple visits).

I think a good part of this is that I don't come across as your average 'easy to rip off' tourist so that may very well be why so far taxi drivers have been pretty good to me.
