Apparently this is a debate about the use of the word "adulterate" when discussing a scheme that made petrol pumps charge the wrong amount of money for the fuel that was dispensed.
It's basically a petty argument regarding one word - "adulterated." The person doing the arguing is saying that "adulterated" is the wrong word to use in this sense, because that implies that the petrol was somehow diluted or tampered with. But, in fact, it was the petrol
pumps that were tampered with, so the fraud scheme should be called by a different name.
I hope this explanation made some sense.
(By the way, it took some serious effort on my part to use the word "petrol" in this explanation..... It's always called "gas" or "gasoline" where I come from.
