The starter motor on the car produces greater sparks and higher risks than anything like re-filling while the engine is running or using a mobile.
Not an issue in my eyes,
There was a program on several years ago where they filled a caravan with containers of petrol, put recoriding cameras inside and then put a mobile phone in it.
They rang the phone whilst observing the picture on the camera.............needless to say nothing happened!
I was in in Tescos petrol station a few weeks ago, by the fucking air/water thingy, on my phone with the window down, some bloke comes across starts saying u cant be on your phone, and i said fair do's ill do the window up, and he said no thats not allowed either!?!?!
The average chimp that takes your money in a petrol station knows nothing, monkey see, monkey do as the saying goes
