Good job on actually thinking about this. Many PAX who sit in the exit row don't give any attention to their responsibilities. I always guilt them by asking them if they door goes on the seats in the row or gets thrown out the door when you open it. They usually smarten up then. I also get extremely pissed when I see some grandma/grandpa sitting in those rows. If you're some little old lady, its dangerous to EVERYONE on the flight if you take one of those seats.
