I will ask the owner of the nearby gas station who does any minor repairs on my car. They are Indian, and a very nice guy. He frequently doesn’t even charge me a dime for small things such as changing my wiper blades (I brought my own wiper blades but could not install them due to an injured hand). I am SURE he will know who the competition on the next block is, especially if they are Indian.
Interesting question I never asked. Who buys ISIS’ oil? Well, dam, this would be an exciting job...
