I know you have seen the signs in bathrooms to turn off the light when leaving. There are instances when I disagree!

There should be a law that prevents one light switch from controlling the light and the exhaust fan in a public bathroom. We are forced to decide between saving electricity (by turning off the light) or save the next visitor from a vicious gas attack. I worked at one place where there was a box of matches in the bathroom and you were supposed to strike one to clear the air. I often wondered when the explosion was coming. My question to you is should you leave the fan(and light) on or turn it off. This sign was posted at a public bathroom I visited yesterday. What would you do?

Oh ... we would also love to see funny signs you have spotted in rest rooms.
