Have the check ready to deliver once you've sent for dessert, coffee, etc. Print their checks after you send the order, desserts, coffees, etc. and place in a check presenter. No guest wants to wait for their server to return with their check so it helps to always have it on the ready. One minute to a server may feel like five to a guest.
