Saw some of these guys this morning in SEA right by D1. Sort of weird, I didn't really get what was going on. They had a golf cart decked out in in garland and a few people dressed as elves. The best way to describe what they were doing is something like "candy striper for airports." They are giving away trinkets, laughing and conversing with those waiting, and generally spreading holiday cheer.

I was just passing by them and ended up with a novelty set of cards. A little strange, but in a fun sort of way.
