Reasons to hate (OK, be mildly irritated at) Michael Grade?

This week, an ITV production company are in my workplace, filming a series called "Trinity" (well, that's what the propsman who I asked said). The main immediate results are that a) the back quad is always full of actors, technicians and equipment, and b) they've taken over the staff carpark too, meaning we're all parking in the overspill car park, which is unsecured, full of potholes, and a stiff walk up a steep hill away from the main building.

If anyone wants to see where I work, look out for "Trinity" (although I'm not sure how much of the building will be visible in it).
