I've never been charged *once* in the decades of letting my tanks run

to let it go completely dry, or they have to do something special.

I'd sure like to know what you've been told 'cuz as I've said, for
decades I've been running mine until the grill flames die, and no one
- not BJ's, U-Haul, the local rent-all places or anyone else that
fills propane tanks has ever said anything to me.

Okay. It went something like this:

If you bring in a tank that has absolutely no pressure, that means we
have to purge the air out because it may have some humidity in there.

Just because a tank runs out of propane does not mean air has entered the
tank.It just means the internal pressure(of propane) equals outside air
pressure.
The tank would have to have a lower pressure inside for air to enter.
That aint gonna happen.

It does if you leave the valve open!
