Density of population in a society with limited products and services rewards aggressive behavior when purchasing and using transportation. If you wait politely to get on a bus, you will never arrive home. Before the inclusion of the 'bakery-like' number system in Chinese banks, teller service was non unlike the floor of a commodity exchange, customers yelling and waving for recognition.

This boorish behaviour is what leads them to getting a bad reputation in places like California and Paris. The tour guides at places like Universal in California and San Francisco are at their wits end with their behaviour. Certain hotels have banned kettles as the chinese are apt to cook noodles INSIDE them!
