I agree with the people in this thread who are trying to promote gaming clubs, you wont have any of these problems in such an environment.
Facts of this thread is the GW manager wants an increase in terrain sales. The OP disapproves of the changes to his adopted gaming environment and is threatening to take his business elsewhere, which is perfectly within his rights.
I found my enjoyment of the hobby increased when I took control of where and how i played my games, I went from a busy, loud and controled store environment, to playing at a decent club and amassing a large amount of home terrain. I recommend that the OP does the same.
