Unforgettable?

I went to pick up dinner from Sushi O Sushi tonight. It's a very good restaurant, and there was quite a line for both seating and take out. And as I was waiting for my food, one of the waitresses came up to me and said, "I remember you! From the airplane!"
Apparently, she had recognized me and was trying for the past 15 minutes to figure out from where. (It was quite a wait for our food.) But all she could say was "yes, yes, that's how I know you," and I really thought she had mistaken me for someone else.
But eventually she was able to articulate further, "on Christmas" (yes?) "on Southwest" (ok?) "from Ontario" (whoa!). She really did have a good memory, which she was proud to admit, "I have a really good memory!"
Turns out she was sitting in the row behind us, so we had never even met. Cindy and I each had a baby in our lap, so with our neighbor in the third seat that made five people in our row. There are only four oxygen masks that drop from above, so I had to take one of the kids and move to another row. The lady/waitress behind us remembered us all from the commotion of changing seats. She didn't know why I had to move, but thought the airline was being mean for separating our family.
Small world. Good memory. And then she was nice enough to hurry our order along because I had been waiting a while. Maybe she remembered I had kids waiting at home.
