They have some like this - the one at downtown State College that a few people have referenced above was only the food bit, no gas. I worked at a Sheetz in Westmoreland county for 5 years and can confirm they do not want to be in the gas business. They're always trying to push over into just food, and encouraged us to act like we worked at "A restaurant, that just so happens to sell gas". I wish they'd open more food only locations. Also they have a sheetz drinks food truck (only made the shakes/smoothies/hot & cold coffee drinks) that they'd travel around to different public events, like the PGH marathon and whatnot - worked in it once and it was so chill while being nonstop busy, definitely an interesting experience.

I lived there when it opened! It blew my mind that a city cared enough to add non-car infrastructure. Such a quality of life change.
