My coworker stated that he had a five-dollar bill in his pocket. I jokingly made a snarky pun along the lines of, "So, you have five-dollar bills". Arguments ensued.
My argument for the grammatical rules were this example:
An ATM only carries Twenty-dollar bills. (outdated info, but just as an example)
You would say that the ATM has twenty-dollar bills (regardless of how many individual bills are in the ATM... if the ATM only had one bill left, you could still say that the ATM only has twenty-dollar bills.
My coworker's argument is that one could not say that he has five-dollar bills but rather that he has 1 five-dollar bill or that he has five dollars. Now, in both of his examples, I would say that those are valid.
Q. Is it valid to also say that he has five-dollar bills even when he is only carrying 1?
P.S. and more examples: A bank, has one-dollar bills, and five-dollar bills, etc... if the bank were out of money except for a single dollar bill, could I still say that the back has one-dollar bills?... why/why not
For clarity, I'm not looking for a work-around. The effect of confusion in this case was desired, though, I can't seem to find the actual governing rule of grammar that covers this. I do appreciate the suggestions though.
