Maybe you need my van.  It almost always spills gas when the pump clicks off, so there's no temptation to top it off!

I kind of enjoyed full serv in Oregon, It was fun watching gas spray two or three feet when the pump clicked off and hearing the attentant say "Yeah, all Vanagons do that"

Is there a cure, or is this really a design defect?
