Specifying the name of a guest in a check In the check view panel, double-tap the name of a guest. For a customer without a specified name, the default name of a guest is GUEST 1 where 1 represents the order the guest was added in a check. Note: Opening the Guest Name on-screen keyboard only works for a check with more than one guest. In the Guest Name on-screen keyboard, specify the name of a guest. Tap Enter.
