In PHX, security check point:

My SO is going through the line right before me with his boarding pass.

TSA Lady (term Lady is used rather loosely on this one): "What does "Gold" mean on your pass?
SO: That I fly a lot
TSA: Oh, I had no idea, I always see these people with Silver, Gold, or something else on their boarding passes, and I always wondered what it means.
SO: <looks back at me, almost laughing outloud at this point> Are you new to TSA?
TSA:No, Ive been doing this for almost a year now.
TSA:<now looking at my pass> wow, there are a lot of you, but yours says "Platinum", what does that mean?
ME: ummm, same as the one you just saw

Do I need to comment?
