Psychological experiment or flippant behaviour

This is the set up:
Time: late morning
Place: headhunter's office
Purpose: discuss a potential role as a leadership slash talent management director

I arrive just in time for the meeting, which was initiated by the consultant. I'm put (yes, put) in a meeting room by the receptionist. Ten minutes later no one has arrived. I decide to leave if they keep me waiting for another five minutes. After twelve minutes the consultant arrives and makes her excuses for keeping me waiting.

That's when I decide to try out the approach of not providing her with the automatic "don't worry, it's OK" response. I decide to say nothing. Because it's not OK. And she knows it. She gets seemingly uncomfortable and she works hard to get rapport after the awkward start. To her credit, I think she is doing pretty well and I decide to change my attitude.

After two hours of grilling, scrutinizing and reasoning we wrap up and again she apologizes for the late start. This time I forgive her.
