Actually I do have a story similar to this. It happened the first and only time I agreed to meet someone I “met” on POF (Plenty of Fish) online without seeing a picture of them first. We had emailed back and forth and talked on the phone prior to meeting and decided to meet at Starbucks over a coffee.
We arranged a time to meet and discussed what each of us would be wearing so we could recognize each other. I went there did not see anyone who matched her description but did see a woman who looked her age and body type height waiting in a corner. I hung around for about 20 min while I had a coffee and did not see her so I left figuring I had been stood up.
I phoned her after the meet and she said she had chickened out on the meet. I did not bother to communicate with her further. Some months later I noticed her profile on POF again this time with pictures. I turned out that she was the lady in the corner of Starbucks in disguise. To me that is just weird behavior for a woman in her 50’s. I kind of felt like I was under surveillance.
