Coming back into the U.S, and flying on domestic carriers after spending time away on foreign airlines. After recently spending several weeks on a variety on international and domestic Asian carriers and having lovely service, I came home and boarded a Delta flight. The FA "greeting" everyone was standing at the front of the plane eating a sandwich and not saying hello. And I was rewarded in first class with a warm bottle of Dasani water.

Aso, people watching things on their phone/Ipad/computer with out headphones. I see it more and more and it is so incredibly entitled.
