A Cape May spouter has a lot of nerve dictating the size tip for patrons to leave who eat at the bar instead of the table. The tip is based on what the customer perceives is right, not what the server does. It is true that servers and bartenders rely on tips to make a living wage, but tips are properly known as "gratuities." Gratuity - 1. (Commerce) A gift or reward, usually of money, for services rendered; tip.
