Thanks to Dave Liquorice for the regs which I have printed off & will now carry in my glove box! It occurs to me that the regulation might be a Term of Supply by the petrol company, not the Government or the licensing authority - just guessing, mind.
I have a couple of VERY unusual petrol cans which I found in the skip at the Anson Museum & ran off with them after asking Geoff. Made in steel sheet & painted bright red, they are round & have complicated but very secure caps. One holds ten litres, the other fifteen (IIRC) I was on my way to an event & stopped to fill them at a rural station. I topped up the car & filled both tins by dint of opening the tailgate on the Volvo. The lady on the pump didn't stop me as (I suspect) I'd started the purchase by topping up the car and she wasn't sure where the one ended & the other began. She was not a happy bunny though & demanded over the intercom that I show her the can. I lugged the smaller one in & she said "That's not a proper petrol can". I pointed out that it had all sorts of dire warnings stamped into the container & that the cap was sealed to a far better standard than a "proper" petrol can. The fact that it originally held acetone completely passed her by! She then demanded to see the other. I told her she could come & look at it in the back of the car but I was not going to carry it in for her. No, she was on her own & couldn't leave the till.
The queue was getting restive by now & I suggested that if she was that fussed about it I'd just pay for the petrol in the car & leave her my name and address so the company could bill me for the petrol so she wasn't responsible. I can be pretty convincing when I try & produced a business card as I spoke.
There was muttering but she swiftly took my credit card with ill grace and black looks & the sale was concluded promptly for all the fuel I'd pumped. What a surprise ;o))
The other thing that happened recently was at Reading services on the M4. There was no pump free with the hose on the side I needed, so I just reversed in. Seemed obvious to me, but when I went to pay I was attempted to be torn off a strip by the large, middle aged, female cashier. It appeared that I was not allowed to reverse up to a pump & if she'd seen me do it, she'd not have served me. I was really lucky that she'd not turned the pump off half way through & then where would I be? I was so nonplussed by this, I didn't know quite what to say, so let it go by unchallenged.
However, I had my revenge by reversing the Volvo from the pump & off the forecourt, disappearing from her view backwards around the corner of the building before turning round and driving off. I was surprised she didn't follow me waving a book of regulations ;o))

Kim Siddorn
