What is sad is that I did that very same thing some years ago.
But I turned around and went back to the station and gave them back the hose and nozzle.
The guy couldn't believe that I came back, said that I was the first person that owned up to it. Told him to bill me the cost and he said "not to worry about it, that it happens a lot more than you think". I lucked out on that blooper.
