My method is to swear my fucking head off in Chinese until they put the pump direct into my tank or I leave. Usually filling up in the country, remembering where the non fascist stations are in the city or riding a bicycle avoids this irritating stupidity.

The fact is filling into an alu kettle is fucking dangerous and can cause a flash fire. Only in a completely retarded country like China would you be forced to do something dangerous for safety reasons. They can fuck right off.
