It is clear to me that the waiter has the power to freeze water at will, and that sometimes, maybe when he has spilled birayani down a customer who would have been a big tipper, or a cow gouged at him on the way to work because he looked at it funny, he loses control of his power and ends up showing it to us mere mortals in the form of sudden soft drink freezing.
