I guess some people will find a reason to be offended by this, but it's been put together as a matter of fact observation ! I mean where are all the people that are meant to be helped by these ? The chairs were generally in unexpected places, with no signs of anybody. Even stranger, the chairs were sometimes left in a place you'd have to make an effort to get to, followed by an effort to go somewhere else without help. Or is it just me that thinks about these things ?
