trying to remember
How did you get ripped off ? I very occasionally change money on the street but very small amount and only once or twice in a trip (so far so good)....
it was a few years ago... and i think there were ten peso notes or something like that..that were the same color as another note? I changed $100 US and he did this sort of flash show with lots of bills and when I got home found that I have about $20... felt pretty stupid, ran out to the street, talked to a cop who went looking for him with me and said, hey, look, these guys NEVER work with a casa de cambio.. ALWAYS go to a bank or inside a casa de cambio to change your money. He was right.
I do not think those bills are in circulation any more.. think there were 10 and 20 pesos bills then but how the lowest bill seems to be 50 pesos, am I right?
Anyway, I just think that it is a bad idea in general to pull your wallet out on the street anywhere here.
