I just came back on a trip with a business colleague. I'm usually quite quick. Walk fast, quick check-in at the kiosk, instant check-out with the rental car, etc. The other guy is slow. He walks slowly. He checks in bags which slow things up considerably. He likes to check in very early and waits in the line, not the no-line electronic check-in line.

Does this drive you up the wall? For me, it was fine but I have a slightly lower opinion of the guy now. Boy, is he slow I now think. Before, I thought he only had trouble meeting deadlines.
