The phrase P's & Q's came form early United Kingdom. Often fights would occur from the rowdy drinkers in the pubs. When a fight was about to break, the bartender would shout to the patrons to watch their Pints and Quarts. (P's & Q's) Taken as a warning to the patrons in the establishment , through time has been taken as just a warning in general, as in manners and behavior.
