It not only needs to be addressed but "they" should be FINED! A HEFTY ONE.
Sounds like a LAZY operation. Tractor Supply also has service for LP and they

PS: To underscore the safety concerns...I was standing near the twin 30lb
tanks of my Airstream many a yr ago which had full tanks and were
baking in the sun. I suspect one of the tanks was overfilled perhaps
by an overzealous tech but when I reached up to switch the valve from
one tank to another the overfilled tank decided to "vent" right onto the
back of my hand. I was fairly startled by this(my neighbor two houses
down heard it!) and then the pain hit me! Put me out of commission
for a bit, trust me :[
