getting robbed, ripped off in a foreign country.

When i was 18, i got scammed trying to buy weed in paris. there seemed to be hash everywhere, but we were trying to get some green. me and my friends had no connections. we went to the area where we had scored some hash previously, and talked to a friendly algerian man about some pot. one thing led to another, and suddenly there were 6 algerians surrounding me and buddy. the first guy politely made it clear that if we didn't hand over the money, it was gonna get ugly. we had only brought however many franc's we planned on spending on said purchase, and i decided the prudent move was to hand over the cash. that was kinda funny.
Another time in jamaica, me and 3 others went up to a "plantation" near ochos rios. we got some ganja when the propriator pulled a knife on us. there also happened some seemingly less seedy rastas as well as a gaggle of tourists, and this time i just jogged over to the group, and the guy gave up.
some guy in london once sold me what appeared to be fresh tea leaves. the next day i ran into him on the streets, confronted him... and he tried to sell me coke.
mine are pretty tame, anyone got any good ones?
