Well I did not hear that it was a brewery before I saw the movie. But when seeing the movie it was VERY noticable to me that is was "some real world factory doubling for engeneering". And it already irked me then...without knowing the type of factory.
I read the specific that its a Budweiser brewery here. Had it been a factory for condoms that wouldn´t have changed anything. A factory is a factory.
As Dennis says, there is always that one person who is the supposed exception!
