This has only dawned on me as a possibility last night around 30 years or so down the line. I don't know if I'm BU to think it was anything but innocent or if others might've had similar experiences.
Background:
As a child (11/12 years old) I went with 2 friends and one of their parents to watch a live filming of a very popular prime time show. There were gaps in filming and we were allowed by friends parents to go for a wander round the arena and I suppose, buy souvenirs and drinks etc in the breaks.
Me and my two friends were approached inside the arena concourse by two men and they asked if we were there just the three of us. My friend lied and said yes we were (pretending to be all grown up).
At this point he gave us 3 backstage passes to meet the stars of the show and said to give a message to one of them. He claimed he was the flatmate of this man and to pass a message on that he couldn't make it.
After the show we went to the backstage area and a bit of a row ensued because friends mum and young sibling were with us. Friends mum demanded to be let in with us and she was.
I can't help wondering if something more sinister was going on though. The man we took the message to seemed quite irritated in general and what are the chances that we actually did bump into a "flatmate" inside the arena dishing out backstage passes? Surely he'd just give him a message himself? 
Does this sound dodgy?
