Good reasons/excuses. If it costs you $100 to do it that way then just say so. Don't say it is illegal.
But then again I went to a barber last week and a black man or African American to be politically correct came in and the barber said that I never was trained to cut your style of hair.
In my opinion if he had been a barber for 30 plus years as he stated he never wanted to learn.
But that was his excuse................
