I felt very similar after a R1 interview and was eventually accepted. Take the following opinion for what it's worth because only you can make the decision. Don't project your interviewers style or mood onto how well you did. How do you know you did poorly? If you did do poorly, how are you going to explain that it was your interviewer's fault? I have a lot of trouble gaming out how that conversation would go well for you. The following quote is from an interview on Poets & Quants with Derrick Bolton, the Admissions Director of Stanford GSB:
"You would be floored at how many calls we get from people who say, ‘My interview went so poorly. Can I have a second interview?’ And I am sitting here looking at the feedback and it is glowing. So that person then thinks the interviewer turned in a terrible report and they got in despite that. No, they turned in a terrific report and you just don’t have an idea. There are so many people who speculate on the process who have no idea what’s actually happening."
If it was a student or alumni interview, and they said something very inappropriate or clearly demeaning and unprofessional, than maybe. An admissions committee member? Man, I just can't see that going well.
