Have you used the bowser at YWUD? It might have changed since I was last there, but on that occasion the process required:
- calling a mobile number that turned out to be the number of someone at YPPF
- sending that person a photo of my credit card
- that person giving me the code of a fob containing a card which authorised the bowser
- refuelling and - if I call correctly but by this stage I was 'over it' - then sending that person a photo of the readout of fuel taken/fuel cost on the bowser.
Had I known that was going to be the process, I wouldn't have bothered.
