I'm in NL and had my wallet fall out of my pocket once at one of the bigger train stations. I realized within ~5 minutes, and basically as soon as I realized got a call from an anonymous number. It was the police, who had found my wallet with my ID in it and were calling me to inform me about it. Luckily I was still at the station and could just meet them and got my wallet back.

I couldn't help but feel extremely creeped out, and my girlfriend still to this day doesn't understand why I felt uneasy about it. "But you got your wallet back!", she says. "Of course the police know your number!". Having 0 privacy has been completely normalized, and I'm afraid we're far too late to do anything about it.
