It would be best to treat the instructor with the same respect as you would any other instructor. It's only human to be disappointed, but if you are ever in his shoes you'll appreciate it if the students are watching you show a technique and are excited about being called to uki. If you set a great example for the other students to follow, then you will show a lot of maturity.

I'm not sure why your instructor would have chosen to have a lower level person lead the class. Surely this person has his/her work cut out for them as black belts, not to mention higher ranking black belts, are in the class and will be more judgemental than a class of lower belts!
