Burnt bridges? Those bridges are only burnt if you insulted the people interviewing and in your description I see no hint of that. You disengaged in a mature fashion and asserted your rights as a participant in the discussion. This isn't "being rude". Anyone who thinks it is likely has a very immature view of the world. A job interview is a business negotiation. Emphasis on "negotiation". They changed the terms on you (or rather your expectation) - it's hardly surprising to expect a change of attitude on your end. Frankly, if I ever have someone react like you did to me in an interview I would chase them out the door and take them for coffee. Interviewees that have the fortitude to walk out in a polite fashion are worth chasing.
