You did the right thing in my opinion Cherie, but like AMN I'd have left a phone number for the person to ring.

My DH found quite a lot of money just a couple of weeks ago and he left his number at the closest store. The lady who rang us to claim the money was very elderly. She could not get over the fact that we had been honest enough not to have kept her money.

She was extremely grateful and her happiness was my husband's reward.
