I managed to stop an elderly and slightly confused lady putting diesel in her petrol car yesterday. It was V-Power but I don't think that would have helped. I have to say that I find the V-Power pumps confusing sometimes.
They are confusing... I think I posted last year that I nearly put diesel in my +8. I pulled up at a pair of pumps that were only diesel - one had a green handle and I assume one was petrol. It wasn't.
I spoke to the girl on the till saying that I nearly put diesel in "oh yeah, that happens a lot at that pump'. Brilliant.
