Why are you looking to "blame" someone for an error? Your question suggests that you want to justify your dishonesty. Everyone makes mistakes but not everyone cheats others out of money because of it. I suppose if the error had been a disadvantage to you, you wouldn't have mentioned it? Expect more of yourself Mike!

The clerk made the error., but that does not entitle you to $22, 50 free fuel. 

Hard tobelieve you wanted to buy little more than 1/2 gallon.......i

the moral responsibility is for you to tell the cashier of the mistake,not doing so would mean that the cashier would have to make up the shortfall.

If you are in the U.S., Obama...it's actually a disguised tax.  Here he is at a station in Washington.

A lack of quality on the clerk .  Did not conform to requirements, no prevention, no zero defects , and evidently dont know price of non conformance.  You are not at fault. You have no responsibility. Its a moral issue , if any. Yesterday, i filled up with diesel in Midland Texas. Filled up with 30 gallons diesel at 4.00 a gallon. didnt realize until after 10 miles away my ticket only read 82.50. I dont know. My tank was full. The clerk with the dreadlocks down to below his shoulder was too busy talking with the other hoods in his store, not paying attention to anything.
