What is the strangest place you have seen or met someone you know personally?

As a follow up to my question about the strangest place you have ever seen or met a celebrity I thought I would turn attention to people that you know personally and the strange places or situations where you have met or seen someone you know well. I will give you an example.

A few years ago I was driving home from another city and the journey was 130 miles. The first 60 miles is just this one main road with no towns or anything to drive through and just junctions and side roads leading you off it. I was driving along, my mind wandering and keeping an eye out for speed cameras when standing in a layby with no vehicle was my own doctor?? This was about 100 miles from home and miles from the nearest place, but there he was standing there.

Another example, a neighbour of mine was driving to an airport and getting on a flight to Egypt to discover their cousin was on the same flight and ended up being in the hotel room next to them in a hotel of over 500 rooms and in a resort with a number of hotels.

So where is the strangest place you have seen or met someone you know?
