Your brother is correct and so are you !
I have a friend here in Australia, now retired, who worked for Westfield. His job-to conduct grass roots campaigns against rival shopping centres who may oppose Wesfield's dominance (now the largest shopping centre chain in the world).
Although they have improved after years of complaints, he told me the parking stations were delberately designed to confuse..and psychologically keep people from returning to their car and thus, keep shopping.
Frank Lowy- who with his sons owns Westfield.Arived in Australia from Hungary as a penniless refugee after WW2. Now a multi-billionaire and the richest man in the country. I once went a charity breakfast in Sydney and the main speaker..Henry Kissinger, after his speech battled his way to Lowy to pay homage. Lowy financed the settlements in Israel that cause so much trouble. Paid a $1M the shopping precint in the World Trade Centre 2 weeks before 9/11 and made $5M on the insurance payout.
