We were delayed leaving, no headphones offered to view the screens on the back of the seats (who has plug in earphones anymore?!). Flight felt like a roller coaster for the first 20 mins, then the captain came on and said we had picked up a tail wind and would be landing in 30 mins, so no drink cart. Only then did he apologize for the turbulence. We landed in about 35 minutes and then sat and waited for a gate for almost an hour, once at the gate, we had to wait again for another 10-15 minutes for someone from the ground crew to open the door. It seemed like on debacle after another. And on top or it, the flight crew wasn't even that friendly - not inclined to fly them again unless I'm desperate.
