The thing that make me go is the not-so-frequent-flyers who don't understand how quickly things can actually move in the "regular" line and how much time they actually have to catch their plane.

I generally take the same flights every week for months at a time. While I admit to enjoying small pleasures in life, the following scenerio gives me tremendous satisfaction:

I'm waiting patiently in line (any line; baggage check, security, etc.) for my flight that is leaving at 6:40. It is now 6:05. A person with too many bags and disheveled clothing rushes up to the line completely out of breath.

"Oh My! Can I cut in here? My flight is boarding!!! My.Flight.is.Boarding!!!!! Oh the humanity!"

So, being the friendly and relaxed traveller that I am, and knowing I have plenty of time to spare, allow this poor-planner ahead of me in line. They go through the line and rush off to their departing airplane. I continue my leisurely stroll through security an onto the gate where my boarding row is being called as I arrive. I board, stow my carryons and settle into my seat.

A few minutes later a passenger taps my shoulder; "Excuse me, I'm in the window there, can I sneak by?". Looking up, I see its my old, poor-planning friend from the security line. "Guess you made it in time, eh?" I say.
