No, I didn't.  What is the semantics of "denotes the same thing"?
You're effectively saying, "Next time I ask for the same thing, give
me something different."  What does that mean?  I understand what you
mean, but it requires an explanation which is considerably more
elaborate.  That explanation in turn makes clear the difference.

Well, sorry.  It's not their fault.
