Infact a friend that I bought many games from in Germany (he had his own warehouse and was called Tobias, not sure what has really happened as I know he still has a lot of cabs but I know for a fact he isn't in the German collecting scene) got a lot of stuff from laautomaten. He said they had barns when the games were stacked up sideways to the roof.
This was his warehouse he had on the back of his house!!

This is what it looked like (also this isn't the place, this is a cab warehouse in Italy that was then demolished to build new houses I heard..):
