They set out to reward The Chocolate Bar's frequent customers' love of sweets and their sense of humor at the same time. To do this, they designed a loyalty card with a dental chart on it. Every purchase is rewarded with a punched tooth. After 16 teeth are punched, the customer is entitled to a complimentary chocolate of their choice.
