This scene reminded me of a German home that had the downstairs living room area made into a tavern with beer on tap and a limited menu for what was being served that night.
Sometimes a musician played for tips.
It was a handy place for us GIs to have close to the barracks because the people who ran this little business always made sure we got more than our money's worth.
The Germans had customary "neighborhood walks" where they might include stops at neighborhood taverns along their way.
