After saying he didn't know he had to have a permit and go on about how they have been in business for over a hundred years, I still proceeded to inform him a permit here is required.
Of course no sales pitch was I falling for after him having no permit. He then wanted to use our restroom. I informed him that the gas station is 3 blocks down and the city outhouse is at the end of the block. He said he was going to more houses.
