This shouldn't be amazing, but should be the norm; I try to help the elderly and infirmed by storing and retrieving their luggage from the overhead bins.
When I diet, I offer my desert to others. When I return from trade shows, I distribute lotsa "schwag" to airline personnel who are always so kind to me. Also, for early morning flights, I bring nutrition bars for the gate agents and check-in staff; small gestures of appreciation.

Once, after retrieving our car from parking, we pulled over to help a fellow passenger who was distraught over losing his wallet. In his rush to make last call at the Tiki Bar, he had left his wallet on the hood of his car and raced off. When we pulled up, it looked like lotsa large confetti all over the roadway. He had a month's worth of business receipts, along with his cash, cards, license, etc... crammed into his wallet and now it was all over the road. We helped scour the area and found all that we could. He was very grateful and wanted to treat us to some "adult beverages", however everyplace was closed by then. Saying we'd take a raincheck for another time, we were just glad to help; and it was somewhat comical.
