Had that. My number here is almost the same as a firm's that hires out marquees, which leads to interesting conversations. In London I had the same thing but for Streatham mortuary.

Mind, my father once phoned a plumber called Sid, who lived in a nearby village: "Is that Sid the plumber?" "Yes". "About this job I have for you..." .And this continued for some minutes before anyone realised there were two Sid the plumbers in the one village and their numbers were almost the same
