Emergency Exit

On an aeroplane I usually sit at the emergency exit seat. I really don't know why I do, it just seems to be that way. Today makes the 6th consecutive plane journey in the emergency exit seat.

I'm not tall, I don't need the leg room, and I much prefer to be able to keep my bag under the seat in front of me (which you can't do in the exit seat).

This trip, I double-checked at check-in that I wasn't in the exit seat. "No problem sir, you're in 9, the exit is 11". It turns out that 9 is the exit.

The last trip, they allocated me the exit seat, but I changed it at check-in. However, on boarding the plane the staff take me aside and ask if I will swap tickets with someone...so that I can operate the exit in an emergency.
