At least conservative jews and muslims both wear distinctive headwear, and sometimes grooming, so it's decent odds of greeting one another on the street. Most other backgrounds, not so much.
I agree with this. I'm white from Toronto, Canada. A decade or so ago I worked in Saudi Arabia and as I was walking out of a coffee shop I saw another white guy walking past... so of course he stood out by the way he looked and the way he dressed.
But not only that, he was someone I met up with at 2600 meetings every month in Toronto. We chatted, and he was staying in a compound that I had stayed at a number of times before. It was a total chance meeting, as neither of us knew the other had even left Toronto for any particular gig. Prior to that I didn't even know what he did for a living.
So chance meetings certainly can and do happen. In this case it was actually someone I knew. But we initially noticed each other because we similarly stood out in the surrounding population.
Likewise, during prayer times (Saudis pray 5 times a day!) I would stay in whatever restaurant or cafe and they would shut the window blinds so the religious police (Muttawa) wouldn't see us and give us grief for not being at prayer. Every time, the place always had numerous other white people whom I didn't know and didn't meet. But you could be sure several of us bumped into each other repeatedly at these cafes, despite not knowing each other at all. Our only connection was being white and non-Muslim. Exactly the reverse of what's being touted as suspicious coincidences here.
