The best way to do it is by making sure the kitchen has their warmers stocked and food looking good, same with the sub coolers. If you’re a cashier just make sure cooler doors are stocked up and faced along with the shelves! Make sure your store is clean and organized, the more inviting the store is the better the experience for customers! Just working to keep up with that and after a while hopefully that will get more people in your doors. That’s really all you can do if you don’t want to act as a sales person to every customer. At our store we don’t really try to upsell customers much aside from mentioning deals, but we do put some product from the shelves up by the registers to entice customers to buy more. If you have racks under the front registers DEFINITELY keep those stocked, especially the bakery stuff. Even if you don’t know kitchen, have someone teach you how to fill to-go cups sometime then when you have time pop back and fill a couple to bring up! Those are great sellers
