Two siblings, same chance encounter

A little while ago I went to Amsterdam to visit my boyfriend. While there, we decided to rent some bikes and go cycle outside the city. On our way to the lake we were headed, my boyfriend got a flat tyre, so we started to walk in a little village on the hunt for a bike shop. It was while we were walking that we chanced upon a film set, where they were shooting a cough commercial. While my boyfriend was busy sorting out his bike issues, I approached one guy on set and started asking questions about the shoot. I mentioned that my brother was trying to get into the film industry, and asked about his experiences. He told me that he was going to be moving to London soon, so I gave him my brother's details. Cue a month later, my brother was cycling to work in London when he chanced upon a film set. Eager to make contacts and find work, he decided to approach the team and start asking what they were filming. He then said he was trying to get into the industry and wanted to leave his details in case they needed someone. And when he said his name.... the guy he was talking to realised that he was the brother I had mentioned in our chance encounter not 4 weeks ago in Amsterdam!
