Oh it’s... “Free”?
While on vacation during the first week of summer, I came across an advertisement for the H1N1 Vaccine on the back of a coach bus. It stated “Get your ‘free’ H1N1 vaccine today!”
This begs the question, does putting quotation marks around “Free” (but not as a quotation, of course) serve any function or purpose? Such as:
All these hot dogs are “free”.
