Telephone advice

When I was a teenager in South Africa in the late '70s, I was travelling to England on holiday with my sister. We were waiting for our flight at Jan Smuts airport in Johannesburg when I decided to phone my best friend in a suburb of jo'burg called Bryanston. Whilst I was chatting to her from the telephone booth, I noticed that the man in the booth next door was struggling to use his phone so I asked my friend to hold on a minute whilst I helped this man(who I did not know!). I asked if I could help him and he was very pleased and said that he was from England and had just arrived in SA and was trying to call a colleague. I said 'ok, which town does he live in? He said 'Johannesburg' do I told him what numbers to dial and asked 'which part of Johannesburg?'. He said 'Sandton'. I said 'oh, I'm on the phone go someone in sandton' and told him what to dial. Then I said 'what part of Sandton?'. He said 'Bryanston' and I replied 'OH, I'm on the phone to someone in Bryanston. Who are you trying to call? He said 'Julian L'. I said ' you won't believe this, but I'm on the phone to his daughter!! Come and use my phone and I'll ask my friend to get her dad!'. I went back into my booth and said to my friend ' the man I was helping wants to speak to you dad, can you get him please!'. I've offer thought about this coincidence and woUndered what made me ask a total stranger of I could help whist I was chatting on the phone. I've also wondered what the chances are of 2 people wanting to call the same family from next door phone booths but mostly I've often wondered if the man himself ever thought about what a coincidence that was and how lucky he was to be helped in that way!
