people never fail to surprise me Mark!
I had a woman last week who was moving today - she been after a space for a few weeks and on calling me LAST monday I told her a space would come available on LAST Friday so to call me Thursday and we'd arrange to have her cat brought in on the Friday.
Phone call never came - no contact so I gave space to another deserving (probably more so) cat on the Monday to get a phone call this Thursday.
Woman couldn't understand why I hadn't kept the space for her and whilst I had said call Thursday not NEXT Thursday - it was somehow my fault her plans had gone awry!
As for leaving everything to the last minute - just don't get it bit there again - why do they give us the emotional blackmail too!
