Rick Dale renovates and restores an old Coke machine for Rick Harrison. But Harrison bought the machine from Rick Dale's brother Ron at the start of the episode. No mention of the seller and the restorer being related was made on the show. Ron never mentioned being an employer of his brother to Harrison on camera. Either Ron was acting on his own or secretly representing his brother by selling the Coke machine.
The exterior of the Gold & Silver Pawn Shop was briefly shown on the show "Psych", Season 3, Episode 5 (Disco Didn't Die. It Was Murdered!).
