You obviously haven't been in many {if any}Sheetz as they are a great stop for food MTO {made to order}, snacks, gas and they are exceptionally clean.
Every Sheetz truck that delivers gas to their stores are elaborately painted and washed before every single run.
Sheetz is not Morton's of Chicago, nor Bern's in Tampa, but it is a gas station with fast, good food.
Every Circle K I've stopped at is more a a truck stop and the rest rooms are filthy
I take umbrage with your characterization of truck stops; not ALL are garbage-strewn slime pits filled with the dregs of humanity, there are a number of Sheetz that double as truck stops and they are kept just as clean as any other Sheetz.
There’s a Circle K across the street from the Hotel Bon Ami where I stay when I’m in Saigon.
