What about small sums of money? Most shows go out of their way to avoid discussing sums as small as a few dollars. For example, Handy Manny presumably charges for his services, but we never actually see any money change hands. His neighbor Mr Lopart is sometimes seen counting the coins in his cash register, but we never see him ask any of his customers for money. It makes sense that the creators of such shows would want to avoid localizing the show in either place or time by mentioning money specifically (for example, a 25 cent candy bar would pin the show to the United States or Canada sometime in the 1970s), so this would be an Acceptable Break From Reality.
