Gas stations are full of vaporised gasoline. No matter what precautions people take fumes are all over. Mobile phones are essentially radio transmitters and cause electrical current to flow when sending or receiving calls. The danger of igniting the gas fumes is significant.

There was an experiment on tv once where they put loads of phones in a caravan and poured loads of petrol near them. Then from a safe distance they rang the phones. Nothing happened. Except obviously the phones all rang. Then they ran a wire from the same caravan to somebody wearing nylon clothes. All this person had to do was run on the spot for a bit then touch the end of the wire. The caravan exploded. There you go. It's actually more dangerous to wear nylon near a gas station than to use a mobile.

Because (a) smoking introduces a naked heat source which would ignite the petrol vapour, and (b) there is a chance of a static electricity spark being generated between the mobile antenna and other metal surfaces, which again would ignite petrol vapours !
