What does it mean to "watch your p's and q's?"



beyondcelery July 21, 2011
Also to "mind your pints and quarts," meaning to watch how much beer or ale you're drinking in a pub. The bartenders of 18th century (or so) England would keep track of how many pints or quarts a patron was drinking, so they'd know how much to charge at the end of the night--as well as when to cut off the rowdy drinkers.

Also an admonition to young British children to mind their manners - their 'pease' and (thank)cues.

A type setting term. Back when they used engraved type letters bonded on little blocks of wood; type was 'backwards'. Also a term used for places that sold pints and quarts of beer--which is more relevant to cooking.
