If you are curious how I doged their attempts to dead the interaction....
I basically used the same playbook you use on strippers and other working women when they try to pigeon-hole you into the "customer" role. It was extremely experimental game for me at the time but it worked like clockwork.
And this is what I mean about the level difference between the teacher and student. The average person of my age at the time wouldn't even be thinking on this level or working on the technicalities of game. I mean I couldn't even enter the strip club at that age, but I still knew about how to handle such an interaction based on advice from older guys I knew at the time.
