I was filling up today, and the gas overflowwed and went onto the ground...but from under my car (assuming the nozzle has a hole for vapors/overfill). Has this ever happened to anyone else and if so, did it cause anything bad to happen? I heard about a guy overfilling his tank the other day and his car ran rough. I didn't "top it off," but it happened from just using the handle lock on the gas nozzle, so I KNOW it wasn't my fault.
