I don't quite know how this guy did it, but last time I tried to take my bicycle into a shopping centre - or rather the grand foyer of the library in Norwich - I was asked to leave.
Thus astounded I had to take a photo of this chap who not only seemed to have managed to get his bike into the Apple Store of Cambridge's Grand Arcade, but seemed to be allowed to use it as a comfy seat when test driving the laptop.
I applaud the Grand Arcade for allowing bikes in, or if it turns out not to be the case then I applaud the chap for successfully smuggling his two wheels into the shop. The Apple Store was one of the busiest outlets on the opening of the arcade and does seem to retain a certain degree of footfall, in other areas of the city shops are closing apace!
One other thought occurs to me, I wonder if the chap in the photo could be using this as a sort of hot-desking technique? Office space is pretty expensive (even though there is lots empty in Cambridge at the moment) so coupled with decent use of coffee shops and bars you could have a cheap mechanism for mobile working. ("Of course Genome" you cry, "you are out of date." people have been working like this for years, but give me my out-door working environment in the graveyard anytime...)
(Where else do you think all that DNA arrives from for the scientists to use?)

Ahh GeNoMe, there's a sign that says you can walk your bikes through the Grand Arcade. How things have changed... I doubt you'd be allowed to do that at the dreaded Grafton.
