Yep. When they say "you've got nothing to hide" I ask them if they close their curtains at night. Or if they lock their door. Or ask them for their exact salary

Yep. When they say "you've got nothing to hide" I ask them if they close their curtains at night. Or if they lock their door. Or ask them for their exact salary, how they spent it, and why they chose to spend their money that way. I think many people don't realize how much they value their own privacy and so I try to give them examples to force them value it on their own.
