Which of course it probably was. I have a friend who makes it her mission in life to spot mistakes in TV programmes, especially soaps. She phones me and says, "Did you notice so-and-so left the house with earrings on and appeared in the pub without them" or something like that. I am very unobservant and would make a useless witness!
I didn't spot Zoe throwing the doorstop like a lump of polystyrene, but I did notice Andy Hunter appeared to be as light as a feather! It takes more effort to blow your nose than it took Johnny to chuck him over that bridge!
P.S. I once spotted Gail Platt dash off to confront mad Carmen in a fit of pique - but she was calm enough to put her hair up on the way!
