I must confess: On one of the most crowded days of the season (over MLK, Jr. weekend) a few years back, I was given a class of Level 4 adults who were all eligible for their AARP cards (I won't be there for several decades). As I introduced myself to them, a woman clad head to toe in Bogner apparel asked, "Would it be possible to have another instructor teach us?" Taken aback, I informed her that I was the only instructor available, and why did she feel the need for a different instructor? (I had showered very recently, after all...j/k). She then told me that she didn't pay good money to ski with some 'punk snowboarder half her age'! Mind you, this was a SKI lesson. I was wearing SKI BOOTS. I was shocked; after all, I have no tattoos, no visible piercings (my ear is pierced, but covered by a helmet at the time), am clean-cut, neat, non-baggy clothing, etc. I pointed out the closest supervisor I could find who just happened to be the SSD. After explaining to her that I was the only one available, that I was more than qualified, etc., she sorta of made that harumph noise and agreed to go out with me.
So I confess -- I immediately began picking on this woman, pointing out all her bad habits, and generally living up to the stereotype which she had ascribed to me. When sitting next to her on the chair, I turned my iPod up as loud as it would go (I never listen to music while teaching, but happened to have my iPod in my jacket at the time). At the end of the lesson, I received 4 tips, and one of the men even gave me what he said was a "double" tip to make up for the wicked witch of the east!!
