Chennai Airport, India
Did you ever swear at yourself aloud, and perhaps under your breath at airport security for confiscating your little plastic bottle of water before you board an airplane? India has a unique way of dealing with the thirsty. The security official simply removes the bottle cap, hands you back the bottle and asks you to take a good, big gulp. Provided you don't fall to the ground in writhing pain, you're given back the cap and left to water yourself at will.
