Random Passenger: Excuse me this is my seat
Me: My boarding pass says it is mine, I have 2B and this seat is 2B
Random Passenger: But I always have 2B
Me: What does your boarding pass has on it:
Random Passenger: 4A
Me: In that case, 4A is your actual seat
Random Passenger: But I am a frequent flyer and I alway get given 2B
Me: I am an occasional flyer and I was given 2B and this is where I am sitting
Random Passenger: Why are you so difficult?
Me: I don’t know, maybe because you are so simple!
