I also see it as not a big deal. As a responsible diver I relish the opportunity to learn all I can and benefit from others training and expierience. I have not run into the pushy and/or controlling instructor type. But if and when I do I am sure I will have no problem having a "conversation" with said type.
Other then that I am an information sponge and welcome all reasonable advice and the sharing of knowledge, which is the strong suit of this sport.
