Thompson shows how the public houses provided a setting in which Philadelphians from all walks of life revealed their characters and ideas as nowhere else. He takes the reader into the cramped confines of the colonial bar room, describing the friendships, misunderstandings, and conflicts which were generated among the city's drinkers, and investigates the profitability of running a tavern in a city which, until independence, set maximum prices on the cost of drinks and services in its public houses. Taverngoing, Thompson writes, fostered a sense of citizenship that influenced political debate in colonial Philadelphia and became an issue in the city's revolution. Opinionated and profoundly undeferential taverngoers did more than drink; they forced their political leaders to consider whether and how public opinion could be represented in the counsels of a newly independent nation.
