For all the examples you listed, how often is the result wrong to to lack of communication? Have you ever ordered scrambled eggs and received them uncooked, because they didn’t understand what scrambled means? Have you ever asked to cash a check, and the bank teller gave you…something other than cash?
Those are examples of things that don’t require clarification, ever. Because there is no variation of those that is even slightly common. No one ever says they want scrambled eggs raw. No one ever asks to cash a check in any other way than to receive cash. There’s no common precedent for a mistake here.
But black coffee is, evidently, just enough of a fuzzy area that it happens sometimes. I guarantee you that people order black coffee with cream and sugar, because they either think “black coffee” means “coffee” or because they think saying “black coffee” means “drip coffee” and distinguishes it from espresso.
Yes, it shouldn’t be a problem, but it is a problem. So where’s the harm in changing how you order it and saying “coffee no cream no sugar” instead of “black coffee”? Just don’t say black coffee and it won’t sound redundant.


If everyone you interact with is an asshole, there’s a pretty strong case to be made that they’re not the problem.
Reminds me of the joke about the old lady that called her husband. “Be careful, I just saw on the news that some idiot is going the wrong way on the freeway!” Husband: “It’s not just one, there’s hundreds of 'em!”
With that in mind, that might not actually be cream.
