We had a woman visit a group I belong to from out of town, and I gave her and someone else a ride to a meeting. A couple hours later I found her debit card in my back seat.

I hate having to cancel cards. I'm still dealing with the echos of losing mine back in February[1] (right before moving!) and so I'm calling everyone in the group trying to get her contact info.

Turned out she hadn't even noticed it was gone yet.

[1] AT&T keeps silently cancelling my auto-pay on the new card and nobody can figure out why.
