Rick said in his autobiography that the reason viewers at home see more sales than pawns on the show is because most of the people who pawn things at their shop don't want to be seen on TV.
During filming, the shop is temporarily closed with only a small number of customers being allowed inside.
The popularity of the series increased business so much at the shop that the Harrisons had to hire 30 additional employees and expand their show room to 15,000 square feet.
Originally, they had shot a pilot for HBO. Rick stated in his autobiography that he didn't like it because they "focused on the night window, and treated customers like they were animals in a zoo." He said that this approach was very misleading about their business.
Richard Harrison had been called "Old Man" since he was 38 years old.
