But that said: If the restaurant can't be arsed to provide me with requisite-free information on what god damn food they serve, I can't be arsed to provide my god damn money for their time.
Different eating culture. In China it's not uncommon to eat out every day whereas in the west it's usually an experience (unless you are eating out in McDonald's). Hence, cheap eats places tend to automate to save on costs.
