['I was out shopping with my wife the other day, and I lost my wallet. It was so nerve racking to not know what happened to it.', 'I bet it was! Did you end up finding it or did you have to cancel all of your cards?', 'I was very lucky, and an employee at the electronics store we had been to called me to tell me they had my wallet and I could come pick it up.']
Thats awesome!  I know stores will typically hold onto a lost wallet but calling you is going above and beyond what the norm is.
I lost my wallet while out shopping. It took hours to find it.
