Supplier Cursed Me for Not Paying, Then Begged Me Back

A new crew of workers from Ohio showed up at the construction site, so when I placed the boxed-lunch order I told the owner to throw in six extra bottles of vinegar. But after I settled the bill, he pulled a long face and snapped at me. "That's not how you do the math, is it? You still haven't paid me for those six bottles of vinegar. Even if I skip the delivery fee, you've at least got to cover my cost!" My eyes went wide, and I stared at Boss Chavez, hardly able to believe it.
