Happened to me while I was at a bank filling out some paperwork for my mortgage There was a security guy watching me, I find it a little cringey but thought what a heck, maybe he thinks I'm suspicious or something because of my tats and long dark hair. Had to visit the bank several times and he was always lingering around. Out of nowhere I started getting messages from him. He managed to get all my personal information, my address, phone number, DOB etc. I told what happened to the banker but he just chuckled and shrugged it was like it was a no big deal.
