Behave boorishly, receive appropriate treatment. Waving a hand and screaming "sumimasen" or its equivalent in any language, outside of Japan, will result in well-deserved treatment. Not discrimination by any stretch of the imagination. I've seen middle-aged and older Japanese women behave this way in France and Italy. Many lack awareness of basic politeness standards common in other countries. Indeed, too many seem to think "anything goes" and that Japan is the only country with observable customs and standards of behaviour. How wrong they discover they are.
