What's worse than spending 2.5 hours laid over in Phoenix Sky Harbor Airport en route from SAN to PDX?
Arriving at gate A25, walking all the way to scheduled gate B10, hanging out in a bar nearby to wait out the 2.5 hour layover, Paying over $8 per beer, then discovering, right as the plane is supposed to be boarding, that the gate has been switched back to A23, and having to run the distance all the way back to A23, which happened to be 2 gates away from where I originally arrived (see hi-res image linked above).
Thanks for making me run some useless laps.
