CanCarrier's Lost and Left Emporium

This fascinates me. I mean, how do you get home if you accidentally dropped your crutch in the street? 

Or perhaps a mugger stole it thinking it was a special crutch. One of those Japanese sword-crutches. 

Or perhaps there was a miracle and the owner experienced a healing crisis and abandoned their crutch with a joyful cry! 

Or perhaps... actually I cannot think of a legitimate reason for there to be a NHS crutch in East London Street.
