45 minutes £180
60 minutes £300
Err not sure how that works. So the extra 15 minutes is £120...No I dont think so either, as much as I like you Jessica. 
Alas, gentlemen, numeracy was never my strong point.

I am very relieved this came to my attention, and have amended my mistake. Most grateful to you all, and even more so for taking the time to review. Fantastic to see when I'm doing my 'craft' right, likewise if and what I'm doing wrong.

I have no recollection of writing that section, nor any reasoning for the madness. I challenge anyone to find a more expensive 15 minutes - other than train journeys, of course.
Thanks again, Jess
