How does one manage to screw up the order, "Large black coffee"?

I don't often treat myself to a second cup of nature's fruit juice, coffee. But I'm sick of the local Dunkin Donuts screwing it up. This is what I'd like to do to that building, I think whoever owns it, deserves it for not training their employees, or managing their business.

Now I've got freaking cream, and even worse, sugar, screwing up my buzz. Argh!
