So this morning at work as I chained up the ratty nineties hybrid I spot the bike on the other side of t'Sheffield rack has a brake cable down to three strands. I'm a nice chap at heart so I leave a note telling him his cable is on its last legs.
Leaving work, I unchain the ratty hybrid, but it goes nowhere. The lock that was on the other bike is...threaded through my luggage rack. Lucky I carry tools. I remove the rack, free the hybrid. I get a biro off a nice Aussie cyclist and put a note on the rack;
'Dear colleague. I hope the brake cable snapped and you are dead. If not, please give my luggage rack to Greenroofer.'
On the way home a startled moorhen ran under my bike. Between the wheels. And I got wet. Bah.
@Greenroofer - I'll call round on the 17th. Sorry about any fuss.
