@MikeK , typically if a customer wants me to use some material that they have purchased, the negotiation stops right there and I send them on their way. Most of us that do this for a living develop a system that works for us where results are as predictable as possible, that's what's needed when running a business. I don't think it's right for anyone to bash technicians for not allowing their material choices to be dictated to them. The customer is right, up to the point where they try to tell me HOW to do my job. They can tell me WHAT to do all day long, though.
@ksungela All that said, it's very cool the the tech in this instance is agreeing to try something new to him that we all know is better. I would not blame him if he gets more runs than normal or anything like that though, it's part of the learning curve.
