The first time we had beer in Australia, Mandeep asked for a opener from his friend who was treating us. We did not know the concept of a twist top cap at that time but now I feel it is quite a nice one. I don't know why we don't have such caps on beer bottle in India. Any one working in the beverage company would know what sort of means people use to open a beer cap, using their teeth, the bracelet, the lock of the car and what not. The only possible reason I can thing is that maybe they get some sort of sadistic pleasure out of it.
