Paying for one seat, getting .75

I haven't told any interesting stories about my holiday yet. I'm going to rely on jogging of memory from Braunwin a little, but the first one happened after I had left, so Braunwin wasn't there. I arrived at check-in and noticed I had the option of changing my seat. So I did, to one that had an empty seat next to it (at the time of changing...). I was quite pleased when I arrived on the plane and discovered the seat was still empty. I sat down for about 10m,the seat was still empty. Then, after a small child had made a welcome announcement - "Welcome to jetblue. We're glad to have you. (mutter in the background) Thankyou for flying JetBoo" - the largest man I have ever seen lumbered down the aircraft. I feared the worst. I was right to do so. I spent the rest of the flight with my left arm on my right side, looking out of the window, in an attempt to suggest that I didn't mind being pressed against the side of the plane. I was on the verge of asking him for $20 for the proportion of my seat that he had used, but in the long run, I felt the damage to the image of my country that would cause was probably worth more than the damage I'd save to my wallet. Or possibly the damage I'd cause to my face....
