I worry a bit about aircraft maintenance when my seat back jiggles and won't lock in position. The aircraft attendants basically ignored us the entire flight after a once through, which worked out, actually. No one ever came back to take payment for the glass of wine I got, and there wasn't a landing prep sweep of the cabin, which meant no one made me turn off my Kindle for the last 20 minutes (what a silly rule).
