Reminded of this after seeing ads on tv for the Coronation Street tour.
I went on the tour a few years ago and we decided to have a snack at the on-site cafe before going in. It wasn't on the menu (think they missed a trick there) but I thought it would be funny to ask for a 'bacon barm'. Channelling my inner Fiz or something. The server just looked at me as though I had two heads.
