I prefer water often, too. But unlike most people who like it chilled, I like it right out of the tap at whaterver temperature it comes out. Where I live it's rarely very cool.
When I'm dining out I ask for a glass of tap water and boy is that hard to get! lol I ask for just a glass of water from the tap, no ice, no lemon. I ask that it come from the tap and not from a machine. I rarely get that, even though I ask explicitly and even in a small place that isn't busy at the time. The wait staff seem to want to make my water special when I like it plain.
Machines like soda or tea dispensers and ice machines---generally filthy. Consumer Reports did a study and the 2 dirtiest places in an office environment were the ice machine and the push buttons for the elevators.
Bottled water? Comes from a machine, no thank you.
Lemon--I don't think the lemon is washed, yet it is cut up on an unkown surface, grabbed up with a bare hand, and stuck in a bowl in the fridge uncovered until it's plopped into my drink. yuk!!!! lol
Just plain old water is all I want.
