We have several. Casey's are pretty common. Git 'N Go, Cenex, BP and Shell are around too.
Shell, it's the only one we trust. The others suck in our area.
There is a few in my area. Uni Mart, Minit Mart and Sheetz.
Sheetz has the best made to order food of the three.
We use the gas pumps at our grocery store Kroger.
But we have Shell, Exxon, Sunoco, Mobil and a few more.

Exxon

We have Turkey Hill, Sheetz and the all time best, Wawa.
