Our store has a pretty good slice business. We slice 16" pies into 6 and sell between 25-40 pies between 10am and 2pm. That’s a big slice, but we charge appropriately. We may get a price complaint from time to time before, but never after they eat. I use a double shelf Hatco warmer just like you see the pizza displayed at Costco with both bottom and top heat. We do throw the occasional pizza away or a slice here and there if they start to look dried out, but the display to the customer is spectacular. During lunch we have 6 going, 3 with multiple toppings on the top shelf that are right in the customers face (we have a piece of 1/2" glass in between) and keep pepperoni and cheese on the bottome shelf. We serve these directly without ovening them. Customers really don’t want to wait, especially the working guys who only have a limited time to eat, so that fastest item they can get is a slice and out the door.
We do not discount slices, we do not do slice specials, our competition does.
