I didnt catch the fact that this is a 13 year old thread and started reading at the beginning, anyhow why do people think water should be free? The establishment pays in some manner for water whether it comes from bottles, the faucet, a lake, river, or a puddle in the alley. If it doesn't come from a plastic bottle which is probably the most expensive water someone needs to put it in a glass, likely with ice then that glass has to retrieved and washed. Someone has to scoop it out of the lake, river, or puddle out back in the alley and most likely want to get paid. Its time to just pay for the water without complaint and be happy that the establishment that gets rich on water sales is still open for your enjoyment.
PS I am also not coming down on the OP, I pretty much assumed it was intended to be humor.
