Wally's Filling Station was the only gas and automotive station in Mayberry (although one is mentioned in "Stranger in Town" and another is mentioned in "The Loaded Goat"). Mayor Roy Stoner's brother is the owner of the gas station in "The Loaded Goat" episode. Andy and Barney would stop by for a bottle of pop, and on occasion Opie would stop by to get air in his bicycle tires. Water and air is free, but they do charge for gas. The filling station had minor thefts through-out the years.
