Your interview bombed. Maybe it wasn't your fault. Maybe it was their fault. But if you have one interviewer distracted and not even worth worrying about showing you the common courtesy to leave before having another conversation, and a second interviewer is irritated (even if it is at the other person, and not irritated at your), then you have interviewers who weren't impressed by their experience in the meeting. That doesn't look well for you.
Keep in mind that non-excellence could just be an aberration. For instance, I recall I had a job interview once where I took a test on a computer, and so I was in a little-used lobby area near the front door. The main work area was free of irrelevant loud sounds (as this was a call center). Some loud employees went nearby that lobby area and made it hard for me to hear the recordings as part of the computerized hearing test. I ended up getting the job, and learning that they really should have stepped outside before being that loud.
In your case, though, this wasn't some low-on-the-totem people who were acting unfortunate. These were the interviewers, who are often people you report to.
If something goes poorly in an interview, there is rarely forgiveness. Case in point: I remember my boss describing an interview, where he asked something that unknowingly touched upon the recent death of the candidate's father. A truly bad coincidence, but what really harmed the candidate is that his response left the interviewer to feel awkward. In our problem-handling department, sometimes things don't go well, yet standards are high and we're expected to consistently make the best of situations. The fact that this sensitive topics was stumbled upon was a completely unintentional accident. Even still, the situation ended up revealing that the candidate's response was unimpressive.
Whether this sounds desirable or not, the truth is that an interview's results can be harsh. Any ounce of imperfection seen by a candidate may, or might not, cost the candidate considerably. (The amount of forgiveness can vary based on who is doing the interview.) If an environment messes you up, that will cost you in some interviews. The best you can be expected to do is to simply try to make the interview be the best possible, and if you don't succeed in this one, keep trying again. (If the opportunity comes up later, you might even want to try again with the same organization. Even many interviewers who will silently judge harshly during an interview, and who might remember imperfection from a prior interview, may still be prone to offer more forgiveness for an incident from a prior time, on the grounds that they understand that growth/improvement may have happened since then.)
