As you enter Port Columbus airport from the parking garage, you encounter one of those exceptionally long escalators with this sign. My God! Is it really necessary to warn people not to try to wrangle a person in a wheelchair onto an escalator and support them as the escalator slowly rises to the next level? Could some imbecile actually have tried to do it — and then sued because no warning sign was posted?
You might as well put a warning sign on a lawnmower cautioning people not to use it to cut hair.
