Some weeks back, I went out on the Tube. Somewhere around Tooting Broadway, I lost my Fitbit. To be honest I assumed it was gone and after pondering, ordered a replacement. But for a laugh, I put in a lost property query with London Transport.
Today they got back to me. They found it! They identified it based on the journey I'd given. And its waiting for me to give the £4 restoration fee to them at Baker Street where it will be returned to me.
Thats rather splendid.
If you lose something you'll want to go to the online Lost Property Office where you can put in your query.
