I once lost my car keys/door keys whist visiting someone in hospital, hubby had to get a minicab to hospital with spare keys. Renault wanted £90 to change locks and give me new keys I declined because I had an M&S security tag on the key ring.
2 weeks later I had a call from M&S apparently a this doughnut of a man at the hospital had found said keys and instead of handing them in had put them in his briefcase & promptly forget about them ! eventually his wife found them and thought he had another woman and had rang M&S I went & collected them from her house about 3 miles from the hospital.
