I've read a few stories about flying in Japan on
Earthrounders: round the world flights in light aircraft. Invariably it seems they think everybody there is very polite, but very used to big, commercial aircraft flying IFR. Radar will happily and politely vector you miles and miles offshore into severe weather and then happily and politely offers you a climb to FL300 to go over the top, handlers will happily and politely charge you outrageous amounts for handling and so forth. Even if you're a VFR, non-turbo, non-pressurized single.
