One of my former assistant's duties was to wipe down the boardroom table each day. Our office was trying to go green as much as possible and since she and her friend are from the younger generation they were especially conscientious in this area. The morning of the Board meeting they made a solution of water and vinegar to use to wipe down the table. Too late they realized their error as the smell of vinegar permeated the room, but the meeting was going to start in 20 minutes. They tried everything, even rewiping the table, but to no avail. It was an interesting meeting with the strong smell of vinegar in the room throughout the day.
