Meeting an acquaintance coincidence

I live in a village in North Oxfordshire with a population of under 2500 people. In the Nineties I was working as a Sales Manager for a Finnish company and was travelling extensively in the UK & Southern Ireland. Around 1994/5 I was on a business trip to Helsinki, Finland. Having checked in, I was walking through the Departure Hall in Terminal 1 when I spotted and waived to, an acquaintance from the village who was in one of the check-in queues with his wife. Having boarded my flight into Business class I was surprised when the same couple boarded into Economy on the same flight. We subsequently had a conversation when I found out that he had moved from the village to somewhere in the Midlands. He was travelling to Japan, via Helsinki, to visit his daughter who was living there. Helsinki was not a common destination for British people in the mid Nineties. Three or four years later, I was on business in the South West and was staying in a Hotel in Looe, Cornwall. At Dinner, the next table was occupied by two elderly ladies and during their meal they were visited by a gentleman who turned out to the same acquaintance! One of the ladies was his mother. He and his wife were in the bar waiting for the ladies to finish their meal.
