I was there in around 1995(?) when it was first introduced. It was called C H Jones back then. I used to manage 3 refuelling sites. It was only the smaller sites which sold it and near impossible to find on the motorway network - you had to divert off route to fuel bunkering sites, often in the middle of nowhere. It’s only been in the relatively recent times that it’s been adopted by most of the MSAs it seems.
