It was facinating to see a pub ran by a landlord at the bottom floor of an 11 floor student dwelling with 16 rooms, 4 toilets, 4 shower a shared area with giant kitchen per floor. Each had something like 3 bar shifts usually taken up by someone else, the thing was "open" all night and beer on the tap was much cheaper than the store. It paid no rent, needed no licenses and didn't have any tax obligations. As no one knew what to do with the pinball profit it was frequently not allowed to pay for beer.
