Back when I was hiring people, I would have probably hired you on the spot, if you said Scheme was your favorite programming language. But that's just me.
More to your point, it would have been fine to collect your things, get up from the table, and say something like "Thank you for this opportunity to talk. I wish you well." or something like that.
Not nasty, not sarcastic, just relaxed and confident.
Cultivating an ability to be genuinely more or less indifferent to what arises in my life (to be non-reactive) has been working very well for me.
