Oh dear. That's most unfortunate Mr Senior.
I believe the terms of the agreement expressly forbade any bodily fluids being expelled upon the U.S. wholesalers section and, as such, it will be necessary to invoke the rather punitive clause 32, section iii), namely, in the event of any bodily fluids being expelled onto the Wholesaler section the hirer shall be deemed liable and subject to a fine of £1000.
So, where are we now mate? It looks like £3,120 + £1,000 = £4,120.
Still got that Robbie Lawson knocking around?
