I'm not sure if this has been said upthread by someone else but: I'm not a fan of Bromptons, so I didn't buy one.
(Didn't like the ride, but also didn't like the bike and how common it was. This was 7 years ago. They are everywhere now.)
Edit: Of course, it I'd got a Brompton maybe
this wouldn't have happened. Probably not, but only because it's unlikely I'd have put 15,000km on a Brompton. Also, I would not be leaving a Brompton outside a supermarket, so I probably would have walked; too close to be arsed faffing around with carrying it in the supermarket.
