Somebody obviously thinks they can make a decent amount of cash out of it. We are working on a scheme (not this one) at the moment and the big change is the increased provision of EV charging facilities plus the need to provide more interest on site as people will be there a bit longer than traditionally as vehicles charge, its why new ones are popping up, as retrofitting is often not possible (and even if it is it basically means closing the existing while you do).
Gloucester Services is just a poor facsimile of the original and best at Tebay!
Poor copy, it's almost identical. They seem to have one floor plan that they use northbound and flip it for southbound.
