Maybe talk to HIS manager or corporate. I'm SURE they'd see it differently. Are you friends with any of the clients? How about seeing if they can write a letter complaining about having to put out $110 PLUS bring their own treats and buy their own clicker?? I think the whole thing, including the poor copies reflects on YOU, not the manager.
I think the letter about having to shell out 2-6 dollars and the poor quality copy sheets is a good idea, BUT maybe start out with having them sent to the Manager himself. Better be diplomatic though, cause this all can cause undue friction between you and he. You know how all of this works - in the end, he has to think "he made the decision" because "he's the boss" and that's why he gets paid the big money!!!
