As I've mentioned before, every other week or so our name tag (and "church" attire) "invites" someone to come up and talk to us--probably 2/3rds are members and the others just nice and/or curious folks.  However, today was a first.  We were having lunch in a diner and when we went to pay the waitress told us someone had already paid our bill.  We asked who and she nodded towards a table where two women were sitting.  We went over and thanked them, and as we talked it was obvious that they weren't members--just nice people who knew we were doing the Lord's work--don't even know if they knew what church we were representing.  Just another pleasant "serving a mission" memory.
