Also, Stay away from the "Shoe" scam..lol
The person will say "I bet you (X) dollars I can tell you where you got your shoes." If you accept the bet he will tell you "you got your shoes on your feet" and then you owe money. If you deny the first bet then the shoe shiner will say "I bet I can not only tell you where you got your shoes but what street you got them on." If you accept the bet this time the shoe shiner will now tell you " you got your shoes on your feet and the street you got them on is (current street)." Now you owe money. If you deny both betting attempts you have just saved yourself some money or a nasty confrontation. :S
