your metal knowledge is impressive. have any books you can recommend to me on the subject? I apologize if I insulted you. does doing the doctor a favor that pays well in the end justify what the patient got? you know that metal won't last, why not tell the doctor that, do the right thing regardless of what he says,and CHARGE for it.? If you had done that, do you think the doctor would still be sending you work?? these are the issues I am having now and need to figure them out before I open my lab next spring. saved the doctors ass at the cost of a ,probably un-knowing, patient?? really? or am I missing something? was the patient 102? or is this the kind of buisness decisions I face in the future?
