I used to work in a photographic shop on Deansgate in Manchester so we'd get a lot from Granada studios.
From Coronation Street we had Bet Lynch, Gail Platt, and Derek who was much the same in real life. Ginger Jenny and Sally came in acting like a real pair of divas, they had an envelope with them full of loose change that was obviously a collection, and insisted on not adding £2.50 to it themselves to buy a much better pair of binoculars that I'd suggested instead of what the could get for the contents of the envelope.
Jack Duckworth was with them at the time and he was completely different, a really sound bloke.
Mavis Reilly came in once and we all looked at her and thought, "yeah she actually looks all right in real life."
We also had Robbie Coltrane when he was filming Cracker, top bloke.
Billy Connolly wasn't really in the mood to joke with us.
Tom Baker came in once and what a laugh he was, eccentric as fark, exactly as he was on the voiceovers for little Britain.
Paddy McGuinness walked past me in Boots once and smiled as he caught me looking at him, "what he didn't know as that I was thinking, "I know him from somewhere," not that I recognised him.
Best of all though, John McGinlay when he played for Bolton Wanderers, he parked next to me in Homebase car park the day before the last game of the 96/97 season.
