One of the last things you think you'll get charged for is the cutting of your cake. After all, you bought it from a separate bakery, and the cake already cost you a small fortune. The fee is really a provision for the plates and forks, and then the subsequent washing of those plates and forks. Everything costs something, right? Fees can range from 50 cents to three bucks a slice. Consider serving cupcakes instead -- they're all the rage, and no plate is required.
