You mean like subway where you just tell them what you want?
Similar, but different. WaWa and Sheetz (a similar business) are gas stations. You fill up your car and (they hope) you come in for a snack. There are usually about a half dozen touch pads around. You pick through a bunch of menus; do you want Hot or Cold food? Snacks or a Sandwich? Snacks will take you to a screen where you pick from things like nachos, what toppings you like, etc. There is an entire menu for different bagels. Hoagies or Sandwiches is another set of menus. Pick your bread, meat, toppings, double meat, etc. Then there are the Pizza’s, Burritos, etc. There are so many different choices the menu would take up the whole wall. With the keypads multiple people order whatever they want and within minutes someone calls their number with the food. In the meantime you can pick out a drink or a bag of chips or other snacks and pay for your items even before the food is ready. It works very well.
