GB is right - its almost always static, but the path is actually to the car body filler hole not the nozzle, which is isolated (or maybe the car to you). You have to try REALLY hard because the vapour is usually above the Upper Explosive Limit. As the fuel goes in, it displaces neat vapour out (we still do not have Stage II vapour recovery at more than a few retail sites the UK).
Rainboe, theoretically yes. See

There are specialist conducting plastic cans and funnels for AVGAS I am told but I dont know how available they are.
The problem is due to get worse because Sulphur levels in fuel are dropping and the industry has had some really bad loading rack fires due to low conductivity Mogas (Sulphur acts as an internal static dissipator - not sure of the mechanism).
Don't get caught out by the desert is dry - Europe is wet thing. One of the worst incidents above was in Sweden in below freezing temperatures where the air was so dry but very conducive to spark transmission. And I have had first hand experience in Johannesburg of static ignitions when I was working there.
Again you'd have to be very unlucky. But you know what Clint Eastwood said.....
