Water Tap

The drinking water tap is different in India and US. In India it is designed in such a way that one cannot directly place water in his mouth. One has to place hand so that water will flow first in hand and then in mouth. Here in US it is different. The tap is placed in such a way that no need to use hand. Water has to directly go into mouth.
Its not important whether I like that of India or US. Because everyone has his way to do it. The wastage of water in the system used in India is less. Moreover it satisfies my thirst better. But there is one disadvantage. What if a person who does not have hand wants to drink. Its not possible in both system unless some sensors are used since atleast one hand is needed to turn on tap. If one has atleast one hand US system is better.
