About 12 years ago I contacted a touring w/g who was in my area offering sub services. Pre punt I contacted her 3 times to arrange a visit, each call was answered promptly. On the day of the punt I had been told to ring her from a certain car park when I arrived.
In my eagerness I got there 30 minutes early, so parked up and brought a paper, as I walked back to my car I saw that behind it was a man sitting in a van and next to that was a man leaning against a motorbike reading a paper.
At the agreed time I called the w/g this was not answered, within a few seconds of the unanswered call I saw in my rear view mirror the man leaning against his bike pull a phone from his pocket, read a message then get into the van, both then started looking around as if they were expecting to see someone.
Coincidence? most probably, but I wasn't going to take any chances and drove away, once a safe distance away and out of curiosity I tried ringing the w/g twice more, she never answered.
