I've been observing decline in quality of food and services since couple of years at list for flights from Asia (Shanghai, Hong Kong). The food is simpler and simpler. Bread is almost always worn out. Alcohol is limited to one glass per person now.
Last time I flew, I got window seat and just the second we took off, there was shower of water on me just from above compartment. I was terrible, as I wanted to stand-up immediately, but steward signed me not too... I had to squeeze two of other passengers, as to fit with them on 2 seats. My seat and some clothes were wet. After some time steward have stood up and given me some napkins, they also offered free seat in middle of aircraft. They said, air-con system was leaking... So it left me to wonder what else was broken on the plane making it home
