Sometime in the 1980's at John Lewis in Oxford St., 2 chaps go into the carpet department and roll up a 12ft x 9ft Chinese rug, worth around £1000. Tape it up, then over the shoulders and down the escalator and out through the front doors.
I imagine any red faces of the perpetrators were disguised by the fact of hefting one of those things between 2, would in any case give them both red faces and sweaty brows!
