Like a bad smell you can help but keep smelling, I occasionally watch "American Guns" for the sheer kookiness of the show.
My inquiry to those that may watch it--after watching it (assuming you knew nothing of the history of Gunsmoke that is common knowledge here) would you want them to build you something?
It would seem to me if I was laying out high 4 figures to 5 figures for a gun, I'd want the gunsmiths/fabricators to be a well-oiled machine, not engaging in petty bickering and corner cutting. If the show is really nothing more than an informercial for the store it would seem that the 4th-grade level snarkery would be off-putting for a potential customer.
For instance, if I have a high-dollar watch repaired, I'd prefer the watch repair man not be screaming at the guy that may go get the parts.
Just an observation about our favorite show.
