Smoking while Pumping

What the hell is it with dumb ass people smoking at a gas station? I've witnessed this again and again, but yesterday some idiot took the cake. This dude gets out of his Lexus and puts his Stunner shades on, lights up a cig, and begins to pump gas! This was right next to me, so you know that I can't let it go:

BikingBeaner: "Umm, looks like you are smoking at the wrong time!"
Cool Guy: "Mind your own business."
BikingBeaner: "I am. I don't care if you kill yourself, just don't drag me with you."

He then does another stupid thing and tosses the cigarette without putting it out. It starts rolling towards another pump so I stomp it out. When he went inside to pay, I kindly returned the butt to his driver's seat.
