Should all Japanese directly address foreigners in Japanese ?

[lexico]

Although in reality the number of short-term visitors/tourists entering Japan with have a better command of Japanese than the typical residents do of English is extremely small, so I agree it is up to the foreigner to learn a few basic phrases (I can't speak Japanese etc) but neither party should assume any business can be conducted entirely in Japanese nor should the English speaker begin with "I don't speak Japanese" or "Do you speak English?" in English. For purposes of shopping/tourist destinations/airports, there's usually at least one person on standby who is more fluent and can mediate most situations. It really isn't really necessary for one side to 'inform' the other in my view....the foreigner just begins speaking in either language and understanding is either there or not.

Most likely an conversation will be end up being an unholy combination of the two.

I think what you say is closer to the real situation than not. So the solution to the tension that has been addressed in thisthread (and others) could use some formulation of a universal rule (is that is possilbe) that will minimize miscommunication and personal resentment such as Maciamo has described so eloquently. Any thoughts in that line? Obviously the natural good-will, good-wll chemistry seems to have failed in this case....

And why do you say unholy ? It must be just an expression of the difficulty in defining a clear cut solution it seems....as when one reads Godzilla and Vanna White would make strange bedfellows....Can we make it holy in any way?
