In the last office I worked in we had an office beer collection. Rule was, every time you travelled internationally you had to bring back an unopened beer from that country that wasn't already in the collection. Failure to do so meant you had to go and get 24 domestic beers and put them in the fridge.
Some people brought back more than one beer per trip, and we put one of every domestic beer in there too for variety, so there weren't quite as many international trips as the picture below might suggest.
Still, there was over 300 beers there last time I saw it.
Apologies for the shonky phone camera photo.
That brown keg looking thing in the middle of the lower left shelf is Chibuku, from Zimbabwe, and is sold in army mortar containers. And yes, it and the can on top are structural...
