They can only fill to 80 percent.
ABSOLTE BULLSH!T !!
It is call a "20 lb tank" because it is design tested and certified to hold 20 lbs of propane ! Some refill stations just crack the overfill screw and fill until liquid vents. This is usually very close to 20 lbs.
actually by cracking the bleed screw it vents at 80%. I used to have my propane certification for work so we could fill the bottles for the forklifts and other things. the bleed screw is to be used in the absence of a scale to ensure filling to no more than 80%.
here is a Q and A from Texas propane if you don't believe me.
"How does a bleeder valve work on a propane tank?
The bleeder valve is built so that during the filling process, when the propane is going into the tank reaches 80 percent, liquid will come out of the opened valve. This allows the delivery driver to know that the tank has reached its maximum filling capacity."
