Yes, it's in Sweden and they feed them surströmming three times a day, until they mentally and psychologically break them. Only once they burst into actual verifiable tears of pure joy and proclaim it the most delicious food ever - denying on oath that it stinks now, ever did stink or will ever stink in the future - are they allowed to leave and go to work in a randomly-allocated branch somewhere in the world.
At the slightest sign of potential dissent and the mind-control wearing off, they get a putrid herring left in their locker with a gift tag that says "With love to you from Big Brother - stay lucky" and they somehow manage to find their new happy and carry on in a state of automatic ecstasy.
Unlike other companies, they don't have a Personnel or HR department - if disciplined, they have to report to a terrifying elderly lady known only as 'Perfume Pam' and their official job title is 'Broken Chattel in Perpetuity'.
