Well, I can tell you that if you show up willing you got a lot more on the ball than most. And since I'm distributing advice for free, I'll further point out that learning is only ever done by choice- surprise! you cannot force anyone to figure anything out. Some folks has just got to take the hard way. It does NOT mean you have to tolerate them or their company, though. So, if some jack ass shows up at the singlespeed ride aboard a borrowed full squish full carbon with the fancy hydraulic disc brakes and all the gears you could imagine...it's up to you.
What would you do if it was all that AND he had no beers?
