If you do have to walk out, if it comes up in the future at a job interview, all you have to say is, "It was a very, very unprofessional environment."
Just about everyone on the planet has a horror story about a job.
Joe, casting couched
Bingo.
My goto--which is the truth 99% of the time-- is typically "I've found the environment to be unprofessional and not goal oriented" If they pushed for details I'll tell, up to a point. It's actually surprise sometimes how much HR people respect an interviewee that refuses to dish dirt on former bosses or co-workers.
"I don't tolerate being lied to, if I am offered a position I expect a fair trial in that position and then a meeting to discuss my performance. I do not want to be shifted to another area of responsibility without a meeting telling me exactly why I am being shifted. In most situations I am willing to take an alternate position. Communications is key here, I'm a professional machinist/programmer I am not going to be happy being told today that I'm the best machinist ever then tomorrow you hand me a mop."
...that's how I got the job I'm currently in. Sadly the communication thing seems to have failed I'm on the verge of giving two weeks notice.
