Our local Sheetz gas station has food (as most do any more). You have to figure out the menu on the touch screen and it is not intuitive. After going through three levels of menus you order an hot dog - if you make a mistake you must start over. Then you wonder if someone behind the counter is paying attention, wait, get your food and pay for it. Oddly, the coffee is self-serve.
Our speedway has an island with food. You use tongs to grab what you want and take it to the cashier. Much faster and certain.
Guess which one I avoid. (Actually, I avoid gas-station food; only had it about 3 times in the past 15 years, but one time with the Sheetz "high-tech" canteen experience was enough to make me a life-long non-customer.)
