I did once head out for an outcall booking to a reg client late one night. No other houses overlooked mine so I decided it would be ok to put on the leather and thigh boots etc he had requested, before I left.
Partway through the journey, I realised I wasn't gonna have enough fuel to get to his house, I didn't have enough to get me home either, or I would have gone back and changed.
I had to brazen it out and fill up at the motorway services. There was no pay at pump facility either, so I had to go in to the shop to pay.
