I ran out of gas late on a sunday afternoon, so I went to a blue rhino site, paid 22 dollars for the propane and an 18 dollar deposit for the cylinder. Now I want to return the cylinder because only Blue Rhino can fill it and I have my own cylinder and I'm told "that's not how that works" and the dealer will not refund me my 18 dollars although I will no longer be using Blue Rhino. Seems I purchased a tank from Blue Rhino that only they can fill. It says right on the cylinder that no one else should fill it. They totally suck!!
