47-year old McDonald's worker and food stamp recipient Reggie Damone found an envelope on the sidewalk containing a check for $185,000.

Being a good Samaritan, he took a bus to a bank and returned the check to the niece of the landlord to whom the check was written. The niece rewarded him with a $50 bill -- .027% of the value of the check.

Here's my money ethics question for WalletPop readers: How much would you have given the low-income worker who found the check and then took a bus to return it? I know I sure as heck would have given him a lot more than $50. And if you receive $185,000 checks, you can afford to be more generous -- especially with those who save you from your own sloppy stewardship of your possessions.
