Re: Respect/Lack there of.
How easy it is to walk into a dojo and be critical... Perhaps next time you want to insure your guest gets your interpretation of proper respect, you can put years of sweat, money, and time into creating the perfect dojo.
As a student who was also in class on Wednesday, I felt our substitute instructor handled things very well. I did not see him roll his eyes while taking ukemi from your friend, even though I was watching quite intently. I did, however, witness you answering your cell phone and having a loud conversation during class. If that's not an issue of etiquette, I don't know what is.
