Instructors can and do read these threads too. And they help form their perspective on who's teachable, or fits their style, or in some cases how much headache a student's "Yelp review" might be in the future. Of course this applies to future buddies, CCR or otherwise too. Some of us have been internet divers for a couple of decades, and we're not strangers. Torching relationships with potential shops, instructors, or buddies? yeah that gets around quickly and the smoke lingers.
Oh, you mean like how you some of you guys treat others so nicely (insert sarcasm)? Like others aren’t going to notice that or do you think you get some dispensation even though you act like a jerk?
