I visited the Czech Republic in October. One night, I went to a Mexican restaurant recommended by the Honest Guide YouTube channel. I sat on the far side of a room in the restaurant. When the college-age waitress walked in the room, she gave a little wave from across the room and was very pleasant. I asked her for recommendations. She provided them, along with good service. At the end of my meal as she brought the check, she asked me if I lived in Prague or if I was visiting. I said I was visiting. She offered to air drop her personal list of places that she likes to visit and hang out, including restaurants and bars. I said okay and accepted the air dropped file. I got back to the hotel and noticed a fair amount of Cyrillic letters and started thinking about the Russian mafia taking over my phone, so I erased the file. The Russian mob to my knowledge never took over my phone.
Paranoid or not paranoid? Would you have accepted an air dropped file from a waitress who is essentially a stranger but with whom you seemed to have a good diner-waitress interaction?
