Staffed and unstaffed are a real difference
Esso Express sites are card-only and often unattended. OpenStreetMap has a tag for exactly that — self_service — and Refuelia now shows it on the station card. It is the difference between a two-minute stop and finding out at the pump that nobody can help you.
Where the count comes from
From the same rows the city pages use: Refuelia counts stations city by city and stores what it found, with the date. No estimate, no extrapolation to a national figure. What the page shows is what was counted, in the cities where counting has happened.
Questions drivers actually ask
Why does the number look low for a chain this size?
Because only the six commonest chains of each counted city are stored. Esso is often in that six, but not everywhere, and where it is not the forecourts are simply absent from this total.
Does Esso Express appear separately?
Not as its own page. It is counted as Esso, and where the map knows a site is unstaffed the station card says so.

Every one of these pages is built the same way and carries the same warning: the number is what has been counted in the cities this map covers, not a national total, and it says "at least" for that reason.
