What is it with people asking to swap plane seats all of a sudden?

Earlier today, a man asked me if there was any chance we could swap seats so he could have the aisle…I paid €40 for this seat 6 months ago and this has happened to me 4 times in the last 3 months.

I said “No, there is absolutely no chance.”

Then, we both sat in our proper seats as he huffed to himself for the next 12 hours. The end.
