So after they totally screwed up the flight there, mech. failure, delays (not for weather),, forcing me to rent a car for $600 for three days one -way and drive 4 hours, everything on the way back was seeminly going smooth, I busted my butt at the customer I was at, job acomplished, I get on the plane and when the drink cart comes by "Ummm.so what kind of beer do you have" "I'm sorry sir, we forgot to stock the beer on this flight" All I want is a friggin beer after I spent 3 15 hour days working. How in the hell do you forget the beer. Idiots. First time on Delta in a while, and it will be my last for a while. And people wonder why the big airlines are going out of business. They suck at customer service.
