Took advantage of the very same thing, Petrus, last year after leaving my laptop on a flight from Dublin. The annoying thing was, I was due to fly on BA1, which was convenient as I live close(ish) to City. However, my laptop was in Heathrow so I had to catch the tube to T5, collect my laptop then zoom back to City! I did feel slightly happier when I was let off with the fee
