Advice;

If somebody meets you to hook you up, and then once you're at the agreed meeting place they say "Okay, give me the money and i'll go and get it" or "I've just gotta go around the corner to get it" then DO NOT GIVE THEM THE MONEY!!. There is absolutely no reason why somebody would need to meet you and then take your money to go and pick it up, and even if there is a valid reason don't go with it anyway because they could still fuck you over.

Unlucky man. Better luck next time.
