What are Honor-System Wine Bars?
Honor-system wine bars are wine bars which operate on the honor system, allowing their patrons to decide how much they owe, and pay accordingly. The first such bars were opened in Berlin by a businessman named Jürgen Stumpf, and they turned out to be successful enough for Stumpf to open more, encouraging the spread of the system to other regions as well. In theory, of course, the honor system could also be used for beers, in regions where beer is a more popular tipple than wine.
