Eric, I get told to "fuck off" from time to time in support / retail roles, and I know elderly patients suffering from dementia in care homes tell the nurses to "go fuck themselves" with optional racial and sexist slurs thrown in. It's just the way some people are. So if you ever want to tell somebody to fuck off, just email me with abusive insults that make Gunnery Sergeant Hartmann from Full Metal Jacket look like a vicarage tea party and I'll file them away somewhere. Then go and write another brilliant article that passes FAC like a knife through butter. Simples.
