I have to go with Art 100%...again.

I would tell the owner what I thought of his attitude and what he could do with his shop. I would make damn sure all the shooters I know would be informed.

Learn to service and/or repair your own bow/equipment. It is not difficult to learn and do, it is much cheaper, often much faster, and you know the work has been done and done right.

Your experience with the shop is why private bow shops are becoming hard to find these days. One pissed-off or dissatisfied bowhunter can do a lot of verbal damage.
