The Petrol Forecourt That Turned Into A Shop

A filling station is now a small supermarket with pumps attached. The reversal happened because selling fuel earns very little and selling almost anything else earns considerably more.

Fuel is a low-margin commodity

Most of the price at the pump is product cost and duty, leaving the retailer a slim margin per litre. Volume is the only route to a worthwhile return.

Because fuel is identical between sellers, competition runs on price alone, which compresses that margin further. There is no product differentiation to defend it.

The site meanwhile carries heavy fixed costs: tanks, safety systems, staffing and land. Those costs have to be recovered from something other than the fuel itself.

Payment was the lever

When drivers had to walk to a kiosk to pay, they were already inside the building. Everything sold to them there arrived at almost no additional cost of acquisition.

Kiosks therefore grew into shops, and the route from door to till was arranged so that it passed the highest-margin goods on the way.

Pay-at-pump threatened that mechanism by removing the walk. Operators responded by making the shop worth entering on its own terms rather than relying on the payment journey.

Location turned out to be valuable independently

Filling stations occupy corner sites with parking, long opening hours and good visibility, which is close to an ideal specification for a convenience shop.

Long hours were already required for fuel, so extending them to groceries added little cost. The station could serve a neighbourhood at times when other shops were shut.

Grocery chains recognised this and moved in through partnerships and rebranding, so forecourt shops began carrying the same names and ranges as high street convenience stores.

The attendant disappeared for a related reason

Self-service transferred the labour of filling to the customer, which cut staffing at exactly the point where margins were thinnest.

Staff were redeployed to the shop, where their time generates more value. The person who once operated the pump now works the till in a room full of stock.

Some jurisdictions kept attendants for safety or employment reasons, which is why the practice looks natural in some countries and archaic in others.

What electricity does to the model

Charging takes longer than filling, which increases dwell time substantially. A driver waiting twenty or forty minutes is a customer with time to spend rather than one passing through.

That favours seating, food and larger retail space, so charging sites are being planned more like small service areas than like forecourts.

It also unbinds the shop from the fuel. Charging can be installed at any car park, which means the retail advantage of the petrol station is not guaranteed to survive.
