According to sources, Arnie is good pals with real estate tycoon Rick Caruso -- the developer who built the celebrity-filled shopping center -- and when Patrick said he was interested in mall management, Rick offered him the summer gig.
But Patrick won't be fetching coffee for people -- we're told he's getting a special crash course in bigwiggery, including running a massive shopping center, from security to public relations ... and he's already doing rounds with one of Caruso's top managers.
It's unclear if the position is paid or not -- but with his parents' combined wealth of about $400 million ... he probably doesn't need the money.
