Don’t you have fill “vendingmachines”? Put some change in, get them filled and next time you go for a fill at the lds they won’t be empty.
Not sure if you are joking, or machines like that really do exist.
It's probably not a rocket science to design one, but unless it can also read hydro stamps and vip stickers, it would be an enormous liability.
