Wal-Mart Mistaken Identity
This is actually a sweet interaction. I was in Wal-Mart and an older lady asked me where something was. I pointed out where she could find it because I am familiar with my local Wal-Mart's layout.
After she thanked me, she looked at me and said, "You really don't work her, do you?"
I said, "No, ma'am." She thanked me again for being nice and helping her anyway.
