If I ever run into a monolingual Japanese speaker that thinks I am disrespecting him for not intending on learning his language to fluency, but having the nerve to communicate in it, I will apologize, and we can communicate with drawings instead.
This would never happen. Japanese are far too polite. For example, a Japanese girl I met last night got all excited and congratulated me on being able to say a very short sentence in Japanese.
