This may get merged with the other threads, but before flying CLE-PHX Saturday I had printed this:

During the flight I asked for a free glass of water and quoted the following:

US Airways says it will provide water and drinks for passengers in cases of medical emergency and during extensive delays. If a desperately thirsty passenger does forget a few extra dollars, US Airways spokesman Morgan Durrant says flight attendants will likely “err on the side of the customer” and give him or her water. After all, the airline wouldn’t want its customers drinking tap water from the aircraft bathroom. That water is safe to drink, just not very palatable, according to Durrant.

“Frankly, that’s just not classy,” he says.

Guess I was lucky and got my one err on the side of the customer/cup of water. I think it was because I cracked the FA up when she head the last part about "classy."
