It occasionally paid dividends!
I had to go to Montreal on a training course, on boarding, the crew names were announced and I heard a familiar name from my light blue days. I asked one of the cabin crew if I had heard correctly, as I knew the familiar name had gone on to become a Captain on said airline; "Is he up front?" "No, he's one of the senior stewards, why do you ask?" After explaining the light blue background, we were invited up to the pointy end for an extended in-flight visit (before 9/11) where we were greeted by a rather foxy and very informative lady F/O. The senior steward involved kept my colleague and me rather well supplied with red wine for the rest of the trip too. 😊
