Found some keys left on a bike yesterday parked near central. Left a note for the owner and also found on the keys a keyring to local healthclub that had a message like "if you find these keys please call xxx-xxxx". Called the number and followed them up a few hours later and they said they had left a voicemail message for the owner. As I had to leave at 5pm I left the keys with a local convenience store. Came back this morning and the bike is still there although looks like someone has tried to move it, note is gone yet still no call or message from the owner. Called police assistance line who checked to make sure it wasn't stolen but said they couldn't call the owner. They told me to go to the local cop shop and they would/could do so from there, so I collected the keys this morning from the convenience store and took them up. My thoughts are that the healthclub does not have their current phone number and that either the note has been taken by someone else or maybe blown off in the wind. Its not stolen so why else hasn't the owner called? Seems that there is no good reason why you shouldn't have your mobile number on your keys yet this doesn't seem to be a standard thing - before I put my number on mine does anyone know why not?
