Mastroquet : nm arg. "Mastroquet" is a slang term to designate a cafetier, the bar or a drinking establishment: originally, it was a wine merchant who served the workers, at the time of the break, half a setier, that is to say the equivalent of a quarter of a liter of wine. This demi-setier, in slang, said to himself half stroc ou my-stroc and by metonymy designated the drinking establishment itself.
By another origin, mastroquet would come from the francization of the Flemish word meisterke which means innkeeper. Very quickly we went from mastroquet to bar then by associating it with a bistro, we arrived at bistro.
