"The customer" infers you now have a 01 Ffl to work on guns for profit. Also that you don't accept guns, receivers, frames for work from those in another state without having that Ffl. Hey remember just a few years ago you were selling that 20 gauge ejector Fox gun, it was too hard for your wife to open and cock? and you couldn't figure that out? Not that many years ago. You've come a long way.
