Phone call

I was sat in the cab of my 44 ton truck backed onto a loading bay at Banbury when my mobile rang, the caller said "Hi is that Bob?" "Yes" I replied. He said "I'm just coming down the hill from Scotch Corner, I'll be with you in 10 minutes" "No you won't" I said "I'm sat in a truck in Banbury". "Are you broken down?" he asked. "No" I said. He then said "Well I've been given this number for a breakdown in Richmond & I was calling for directions to Conan Drive to come & do a home start". I told him "Once you get into Richmond go past the schools, turn right at the roundabout onto Gilling Road & Conan Drive is 3rd left or 1st left past the SPAR shop" He was silent for a moment & then said "I thought you said you were in Banbury?" "I am" I said "But of all the millions of mobile phones in the world that you could have phoned you phoned one belonging to someone called Bob who lives in the same town & in the very next road to the one you're looking for, my road is 2nd past the shop.
