Real estate guy who makes EUR 75,000 commission on house purchase forces me to sit in front because "I'm not an Uber driver"

The real estate guy picked us up to drive us to a €1.5M home to look which if we bought he'd get €75,000 commission

Me and girlfriend enter back of his car

He says “I'm not an Uber”

I say “Desculpa”?

He says “I'm not a driver, you need to sit in the front next to me”

I say “Desculpa, I’ll sit with my girlfriend, thank you very much”

For €75,000 you'll be my Uber alright
