Lemmy, what are your "missed flight" stories?

College freshman flying back home for the summer. Not used to flying. Got to my gate about half hour before boarding. Hungry. Went to closest restaurant a couple gates away, got a burrito and ate at a table while listening to music with headphones. Lost track of time. That burrito had my full attention. Missed all the overhead calls for me. Plane had departed by the time I casually walked back to my gate.
