I am sitting in my favourite coffee shop and one of the members of staff needed to move a chair away from a table to place it in front of a high cupboard so she could stand on it to reach it. She dragged the chair several yards and the scraping noise made me feel like screaming. She then proceeded to do this several more times by which time I felt like my ears were bleeding. Nobody else seemed remotely bothered. My DD gets the rage from the clinking noise made when people stirring their tea/coffee for an excessive amount of time. What common place noises drive YOU mad?
