I'm always grateful when an interviewer shows me this side of them early in the process, it really saves everyone some time, and I dodge a bullet.
In your scenario, I'd have probably just smirked at the (I hope embarassed) remaining interviewers, and said "welp, anything else you guys wanna discuss before I go? Because I think I see where we're all headed here" or some other lighten-the-mood banter. Then we can exchange recipes or new restaurant hotspots, shake our heads at how ridiculous tech can be, and be on our merry ways.
