Another funny story from my grandpa was when he bought a car from the local Honda dealership. He went there every day and lingered around, refusing to close a deal on a car he felt they were screwing him on. He kept this up for a hilariously absurd length of time until the owner himself told his sales staff to just sell the fucking car to him at a $500 loss to get him out of his showroom and that he never wanted to see him in his showroom again. The salesman even showed my dad the books and proved they lost $500 on the sale just to finally get rid of him.
