I had a similar thing happen to me. Was walking through Hyde Park and dropped my phone, train pass,debit card and office security card out my jacket pocket. Didn't hear it fall out because of the grass dampening the thud. Lovely lady found my phone and returned it to me after call someone on my phone list to get my address. Cards and pass etc also found by someone and handed in at the Hyde Park Lost and found. Not ED related but it warms the heart to think that people are so honest to do things like this.
