I have walked out on meetings, presentations, interviews and etc. I'm even audacious enough to tell the referral up front that if its a waste of time I'm walking out so be sure that its not.

Half the time, the reaction is that I've lost 'face'. The other half of the time, I'm praised for my efficiency or speaking up.

You broadcast what you what want. If you want to work with no-nonsense cuts through the bull and tackles real problems directly people, than keep doing what your doing.
