One possibility is that the 50 - year - old was catfished. They thought they were talking to an attractive and interesting person, but when they finally met, it was someone completely different. It could be a much older or younger person, or someone with a very different appearance than in their photos.
Perhaps the 50 - year - old went on a Tinder date and found out that the person was really into some strange and off - putting fetishes. The 50 - year - old was not comfortable with it at all, but the other person kept pushing the topic. Also, it could be that the date was constantly interrupted by the other person's really annoying friends who showed up uninvited and made the whole experience a nightmare for the 50 - year - old.
In this Tinder horror story for a 50 - year - old, the date could have turned violent. Maybe there was an argument during the date, and the other person became physically aggressive. This is a terrifying situation for anyone, especially if it happens unexpectedly. Another aspect could be that the 50 - year - old discovered that the person they were on a date with had a really disturbing criminal record that they weren't aware of before.
