Entire show is staged. I quit german tv like five years ago because some of our biggest channels just air this mind boggingly stupid stuff the whole day long. Either like 3 episodes of the same show or it switches between like let's say a fake judge show with a trial, a private detective show, some family drama, some teen getting preggers, a show about raising your kids properly or t  3ffa  eaching their mothers how to clean their apartments. The last example probably features real people but it's hard to tell. Apparently one of the biggest companies responsible for these programs mass-produces them across europe, so the show might have different names but the logos and certain rooms look near identical. They put out listings to "star" in the shows and pay the "actors" 400 euros.
