Study participants rated menu prices with an automatic percentage service gratuity as better deals than equivalent service-included prices when the service component of price was below the standard 15 percent tipping rate. However, the reverse was true when the service component of price was above 15 percent. Furthermore, a move from percentage service gratuity toward dollar service gratuity impeded participants’ menu price judgment. These findings provide some insights regarding which pricing alternative to tipping should be implemented if and when restaurateurs decide to abandon voluntary tipping.
