I'm going to leak diesel on a customer's driveway.
That's rather rude. Did the customer do something to upset you?
The bastard cheated me and underpaid me for the driveway job I did for them.
Maybe you didn't get the most money out of your work but you shouldn't consider vandalism as a solution. If you are going to damage other people's property, there are legal ramifications involved that you should seriously consider. It might be a huge fine or time in jail.
Some rules are meant to be broken.
I understand your frustration, and it's wrong that they didn't pay you properly. However, there are legal ways to try to get the money you are owed. If they truly didn't pay you the agreed amount, you should contact a lawyer to see how you can get them to pay all the money they owe you.
