Actually this is what caught my eye! They were on the other side of the jetway to E-12, which happened to be my gate of departure. I saw this van with a sign on the front that said "Caution! Children." They sat there for a while and then one man directed the van under the jetway, indicating there was several feet of clearance. A female was driving, then he jumped into the vendor seat and began distribution.

I kept thinking why didn't I have a camera. When I realized I did, (sorry just came off an 11 hr international flight) they were gone.

It was "cool."
