Agreed, I'm getting a little tired of seeing the rather obvious zombie-like response "just find another dive shop" which is unhelpful if local dive shops are scarce or are ALL being 'stupid', unfortunately, although I upgraded from a dial-up to high-speed WWW connection, I'm still unable to get a WWW-based gas fill.
Forget the LDS if they are telling you they will not fill tanks the DOT says are OK to use. The shop CAN NOT over rule the DOT on what is safe to use! If they do report that to the DOT.
