I have a noisy keyboard. A pax in the seat next door went off at me "I paid for this seat to get a good nights sleep before arriving to work"
Of course, I didn't rebutt, "my company paid for me to have this seat to continue to work, so I could ..."
He had a point. If I'd paid 3x econ costs to get some dickwit who cannot stop typing at 3am, I'd feel a tad grumpy.
