The other day I saw a sign in a restroom saying:
Wash your hands thoroughly to kill bacteria and serve safe food
It struck me as wrong somehow, since it gave me the immediate humorous mental picture of the very act of washing somehow actually serving food at that moment, just like the bacteria killing. I also think the point is not to "serve safe food" but rather "safely serve food."
Am I correct that this is wrong, or at least awkward? What would be a better way to say it?
