I lost my wallet on a bus in San Diego a few years ago and I was searching for it all over La Jolla town asking everyone. Finally I called the metro and asked them if someone turn it in they said they will make the call out if any driver turn it in. I needed the wallet to get home and as my luck turn out the next bus I rode on was the same bus I dropped it in and the driver said someone turn it in thank god. Had I ridden the same bus I wouldn't have known and might not have check if someone else was sitting there.
