First off, to answer your question, if I was in your shoes I'd go buy a Lamisil.

Second, are you trying to just share the story or are you trying to console yourself for getting duped?

Forget about the 5 bucks you lost. Problem with these fakers is that there might be somebody who would actually need money. My friend lost his wallet while coming back from work and had to ask people for Subway fare, few didn't believe him at all.

So what would you do next time? Just tell them that you would love to help, but you are out of any dime. Or tell him that you have ID card from 3 people who haven't come back to claim their money.

Last, to Samsara's post, I have a similar one I saw in Break.com (real story).

The bum:"My Friend was killed by a Ninja. Need money to learn Karate."
