Nearly caused chaos on our local tram network by leaving my rucksack on board.
I just walked off and left it lol could have shut the whole network down if someone had got jumpy about it.
Yesterday someone left a laptop in Piccadilly Gardens and the Bomb Squad carried out a controlled explosion on it after stopping all transport and people coming near it.
But I asked a driver and he radioed to say I had left it and I got it back fairly soon.
Doh lol
