Thought this link worth posting, there certainly are plenty of sharpies around who can spot a mug a mile away, as much as you may want to believe your new found friend is fair dinkum chances are he/she has an ulterior motive, take care.
"There's a certain group of travellers who are very easy to take advantage of. They're absolute suckers; total chumps.
You'll see them get themselves into all sorts of dangerous situations and you'll cringe at their stupidity. You'll watch as they get fleeced by people they thought were their friends. You'll see them get robbed or swindled in situations no one else would get themselves into. They're so much easier to fool than the rest.
This group of travelers? Men. Blokes. Dudes. They're the ones who are ripe for the swindling. They're the suckers who will always get done."
DAMN .... I very nearly read all of that.
