Ways not to lock your bike

Nice story.
What kind of social profiling did you use to distinguish the Charge owner from the rest of the Waitrose shoppers?

That's why one should only shop at Waitrose. Went there the other day, locked my bike and noticeed a Charge ... unlocked. I frowned for a bit, "shall I stay and look after the bike" and decide to go in and see if I can spot the owner. See a guy with a courier bag and ask"do you have a Charge bike?" "eerrr yes?!" "You haven't locked your bike". He ran outside, locked and came back with a big smile. I am pretty sure he could have left it there unlocked for a while without any problems.
