Let’s think about this from another angle: do you have some basic building tools? How about if you spent some money on a medical grade scalpel? I bet it would save you a lot of money to build your own furniture for your restaurant; but would it be functional or look good? How about that scalpel? Could you potentially use it to perform surgery on yourself if you were injured? Of course not, the very idea is ridiculous. You have neither the education, additional tools, or the ability to use the tool you have purchased. You would obviously hire a wood crafter to build your custom furniture or go to a surgeon to operate on you. Both people are qualified professionals educated in their area of expertise.
