Seriously. If you think about it.. the controversial service charge that we ought to give to a restaurant after we've eaten our fill, be it a poor or an excellent service, is in fact, essentially, a fee that we pay, for them to watch us enjoy our meals. To elaborate further, if you've noticed, when the waiters and waitresses have finished refilling your glass of chinese tea or serving of orders, they will, instinctively, dismiss themselves to an obscure corner or a cubicle housing utensils, to await for further instructions, while admiring the exhibits - us, eating. It's almost like an owner feeding his hamsters in a cage and admiring them, nibbling on the nuts. We are actually paying them to watch us eat.
Isn't this fucking sick?
Sorry for this irksome interpretation but it's just a random thought.

oh well.. study hard folks.
