Propane..unlawful to have fridge on...is incorrect...

So at most gas stations they have propane filling stations and many roughly 50' away from the gas pumps. They vent the tank/hose pressure hooking up and disconnecting the propane tank :S. Isn't there more propane leaking in that process than would ever leak out of a properly working anything on your RV? OMG the world may end.... naw I will run with my propane stuff running even when filling up with gas. But if your rig has a propane smell turn everything off and get it fixed regardless!
