Rural areas and small towns, where station operators have planned for many customers having larger trucks and pulling trailers, and most of the business is fuel sales.
Suburban coffee shops and convenience stores are the worst, they are designed to trap cars long enough that the drivers will come in to spend $2-$3 for a dime's worth of drink in a nickle cup. That difficulty getting around is intentional, part of a corporate marketing strategy.
I know I can get my C into and through 3 of the 8 stations in my city of 36,000, maybe just one particular pump. Some of the 8 I won't even take my car into because I know I'll be trapped an extra 5-10 minutes, unless the place is almost empty.
Depending on the direction I'm going, I may delay fueling the C until I get to a particular station in a farming community 12 miles out of town. I look for the same type of station while traveling. But then, I'm not usually on the Interstate (scarce out here) and on the Interstate you are sort of trapped by the type of stations built at the exits, and often only truck stops are suitable.
