The capitalization of Do and Not is terrible. Of course. I despise random and inaccurate capitalization.
The lack of punctuation is forgivable but still annoying as hell.
But it's the existence of the sign that bothers me the most. Why taint a perfectly good table with a sign asking patrons not to move it and the adjacent furniture? It's as if the table only exists for the sign asking that it not be moved.
Why have a table at all?
I would submit that a collection of poorly appointed furniture is far more egregious than this plastic and paper monstrosity.
