A truck stop of mine on a model RR layout?

What could be different to make it more authentic? Has any driver here seen fuel stations with one-way islands like mine?

 

Parking? Anything to oblige.There's even a choke-n-puke burger joint and a convenience store. The logic of my pump island directions. Trucks entering from the rural highway northbound have a shorter approach tot he islands so there three lanes are closet to the highway so they have less cutting of the steering wheel. The trucks heading southbound have a much longer approach to the islands so there islands are into the parking lot more away from the highway. They have much more room to get into position to approach their own islands. Northbound and southbound trucks each get three fuel lanes. There is a nearby freight station with a dock. Note the generous amount of space drivers have to maneuver in this industrial complex.

 

The Campbell's Soup double B is approaching southbound: he has the longest approach to pump number one right next to the store since his vehicle is the most massive to maneuver. The cement mixers are in the private parking spaces of Norton Concrete company. It is not just a truck stop but there are multiple industries and businesses on this 5-sided (pentagon-shaped) street block: Norton Concrete, Davidson Intermodal American Freight Co., Don's Diesel, Hamburger Station, KFC, Rob's Motel and Cafe, Groves Animal Hospital, Armstrong Medical Clinic, Cambpell's XX Beef ranch feedlot, a small blacksmith shop and Flying J full service gas station with auto garage. Five of these businesses also have customer railroad sidings.

 

It's in an imaginary town in northern California near the Oregon border of a population of 750: very rural setting. Should all the fueling lanes be bi-directional instead?
