Thats really nothing.

So anyways I work at a hardware store, we fill propane tanks in the back of the store. Like 5 years ago there was a national law that makes it illegal to fill non-OPD tanks. The new OPD tanks can't blow up, so on with the story.

In the back of the store we have a fenced in area that we hold old tanks along with the filling place. So this lady rings the bell for me to fill her tanks, I come out back to notice she has her tank, along with an old tank that was sitting inside the fenced in area because its not an OPD tank. She tells me she wants them both filled, I'm thinking well maybe I should be like don't steal our tanks but whatever.

I explain that we can't fill those old tanks and she can't rid of it at the local trash pick up. So she heads inside to pay for filling her old tank. I also explain that we charge 4 dollars, its a 500 fine to throw it out at the courner. She comes back out I fill her tank, and put both back into her car. She just goes in her car and acts like she's looking for something, so I just hang out in the back knowing that she just wants to drop the tank. So she ends up pulling away, I go inside to tell my boss I'm going to be out back for a few he's like whatever.

As I'm walking back out the door, her car comes back around the building, and she decides to go and pay 4 dollars to give us back the tank she took.
