paul as in hitman?
ifit i will say he comes accross as a genuine honest guy,who has had some real bad luck with his back,he was selling up everything so probably got a better offer or decided not to sell it,i think you should be chatting with him directly and not calling him on here!
I feel that you are going the totally the wrong way about it by coming on here,maybe you should get a backpack as a backup or a trolley as you always need a backup anyway and then your customers wouldnt have been let down!
