Quite topical I guess but I live and work in Manchester and have had the misfortune to bump into Antony Cotton on a few occasions. I can whole-heartedly agree with what everyone says about him being a nasty piece of work.
The first time I encountered him was about three years ago near Christmas. He was on Canal St with Lisa Reilly. I noticed her before I realised she was with him because she was slightly drunk and knocked into me, I turned to see who it was and upon realising it was her sort of did a double take and probably looked a bit shocked. Without me saying anything she laughed and said 'Yes, it's me' so I laughed back at her and said something like it was ok, don't worry about it and was about to say have a nice Christmas when AC pulled her by the arm and sneered at me 'Oh, it's like he's never seen somebody famous before.' Lisa just sort of pulled a face at me as if to say, sorry about him and then we both walked away.
The second time I saw him was in a department store and I'd just finished paying for some stuff when he came up and piled loads of clothes on the cash desk and barked at the woman 'Can I just pay for these and go, I'm in a rush'.
The third time was last December just before Corrie's 50th anniversary and he was walking down Deansgate in Manchester wearing glasses. A few people still noticed him and a woman approached him to speak to him and he just put his hand up, said sternly 'NO!' and carried on walking. Me and my friend were in hysterics, because by that point it was a running joke that he was a bit of a c**t and that just proved it.
I also know a friend of a friend (yeah, I know...) who works at Granada and AC is well-known for his behaviour. There was a point, not sure if it still stands, where a long-running member of the cast refused to have any scenes with him because they could't stand him.
