A couple of questions. Will the wood come into contact with people directly? Will the shelves come into contact with food of any kind? Personally I would turn down the lumber if it was twisted in any way that made it hard to work with. But that’s just me. I have no qualms about turning a job down that would reflect on the product I built. I have told customers to find someone else because what you want built is not in my scope of work, but I would still like to maintain them as a customer just not on this project. You could even suggest someone else to offer up a solution for them.
