I prefer bare hands with most Indian and Arabic style dishes. If it's Southeast Asian food, I have to have sticky rice and a thick curry if I am gonna eat it with my fingers. Shame Cambodia doesn't eat too much sticky rice, because that is well-suited for chopsticks.
I can't blame my friend, I might have just as likely been the one to assume the French bidet was some kind of elegant face-washing basin. Something about the fact you have get on your knees to use it made me think my intuition was wrong. !ENGAGE 25
