Shell's first self-fill petrol station in the South West is opposite Charles Church on Bretonside in Plymouth designed by Peter Roseveare. The Rotunda, here as Turnbull's and later becoming Staples is situated on the outer edge of the roundabout and looks suitably space age. Notice the two-way system and remember your tank does not have to be closest to the pump but gloves, whether filling or at the draughty till, are a stylish necessity and not just for the cameras.
