I wonder if the guys with the signs do the best or not. The best pan handler I ever saw was not one of the sign guys though.
At my old office a guy walked in decently dressed and asked to speak to the manager. I said I am the owner, and he started crying.
He tells me a story about how he and his family were staying in a hotel on vacation nearby. His car had to be towed last night, but he accidentally forgot his wallet in his car.
Needless to say the tow truck people cannot locate his wallet, and he is about to be kicked out of his hotel room, putting him and his family on the street while waiting for the car to be repaired.
He is trying to raise $40-$50 dollars, just so his family can have a place to shower and sleep, and he will gladly send me the money back when he gets back to his home town.
Without even thinking I gave the guy 20 bucks and he hugged me! I felt good because I was helping out him and his wife and kids (I had a newborn at home at the time too).
Two weeks later I saw him working cars in the parking lot as they were going into the grocery store.
My intention that day was to get my money back. Unfortunately, he saw me coming and ran away.
Talking to people that he was trying to work that day, he was using the same story on them. He must have a high conversion rate if he got me!
