Just answered one of those annoying sales calls. It always amazes me that they'll rant on with their name and the company name without giving you a chance to jump in and tell them you're not interested. I usually answer in English - "Sorry which company are you calling from?" at which the person on the other end will immediately respond with "Do you speak Japanese?" in Japanese - which I usually answer with "No." (which gets them off the phone).
Now what strikes me as absurd is that if I didn't speak Japanese then how would I know what they had asked?
The most ridiculous example of this is when a sales guy came to the door and immediately said to me in Japanese "Oh you don't speak Japanese" before I had even opened my mouth. I replied in Japanese "Yes that's correct I don't speak Japanese so you are wasting your time". And he agreed and walked off. I wonder if it ever occurred to him that I had spoken to him in Japanese, so therefore his assumption was incorrect?
Hmm perhaps a funnier story is when my flatmate at the time opened the door and the salesman asked if her husband was home. I happened to be wearing a lumberjack-ish shirt at the time so I walked around the corner to the door and asked him in a deep voice what he wanted. You could see the stream of dust as he ran.
Is it mean to mess with sales peoples minds?
