Most Indian people, unless *very* Westernized, drink out of water bottles by pouring it into their mouths from a height of about 3 inches. They don't touch it to their lips. It is a surprising attention to hygienics in a place not known for it. Even Americans touch water bottles to their lips.
This arises from the fact that communal cups are used in water dispensers throughout India, and the habit of not touching your lips to anything with water in it has been carried forth into use of individual water bottles.
Took me like sixth month to piece this together and understand why they did this.
Don't remember seeing this in America amongst Indian friends.
Just some small piece of random trivia for you....
