I got off at MUC, and the same concierge as two weeks ago had a sign. Not with my name though, so I just kept walking.

However, she ended up on the escalator beside me (I guess Mr. Whatever didn't show up?).

Me: Good morning
Concierge: Good morning.........oh Mr Kennedy! I saw your name on my list! One day, you'll have to explain to me why you do this.
Me: look at the cost of my ticket
Concierge: Ah we wondered if that was it.

At least concierges are interested. I practically have another "I work at the airport" story from trying to get this BP printed
