I'm still left wondering what kind of 'unplanned' meeting a premier league manager gets invited to when, one assumes, his diary is well managed by his PA....
I've been involved in arranging corporate events myself and the contracts on this kinda thing are usually watertight in terms of 'what you ask for is what you get'. If the 'star attraction' doesn't turn up due to a simple diary cock up then, as organiser, I'd be mighty annoyed at best and reaching for my compensation calculator at worst.
