I'm currently in Yunnan, China and one of the cheaper and still very yummy things to eat here is a spicy, oily, rice noodle soup.
I'm used to getting similar dishes such as Laksa at home in Australia with chopsticks and an Asian soup spoon. I'm fully aware ethnic cuisines and eating experiences can get modified to varying degrees when exported.
Here in Yunnan I get a big bowl of noodles with quite a lot of liquid. Normally I would eat the noodles with the chopsticks and sip the soup with the spoon in the other hand. I learned this from watching Asian people eat in Chinatown and in Asian restaurants.
But here I seem to always receive chopsticks and no spoon.
Is it rude to drink the soup from the bowl as though it were a large cup, or do people regard the soup as part of the washing up and not as part of the meal?
I know I can pick it up and drink it if I want, but I want to know if this is either offensive/rude/vulgar/uncouth or just not done for any other reason.
