 And then I connect the propane to the barbecue, and I have a little gauge, okay? And it tells me how much gas I got in there. It gets down to the red. I unscrew it, and I take it back for $19. I fill up that propane, and I'm in good shape. What do you got here? What are you selling me here? I would love to know what this is. How does this help me?
