Elton go back and read the posts on page one? Do you really think they would want to risk all their stock or pay the sky high insurance premiums?
I don't think it would have much of an effect on premiums, because shopping centres have all sorts of things left running all night long so the increase won't be much. Plus they have sprinkler systems etc and are 24 hour manned. And the spaces there will generally be very far from flammable material and comply with H&S.
That's a very different proposition from an unattended scooter (or only attended by someone who may struggle to raise the alarm) in a cramped flat full of flammable material with lots of other human beings close my.
And yes, I do think they would be less careless of their stock than others would be of human life. Not least because neglect of the second is much more likely to lead to criminal charges.
