You're a very gracious gentleman Merrick, it's the main reason I come here. But would you please let me borrow that book for now, and I promise I'll pay you the full £100 later? I'm filthy rich but I left my wallet in the car when I got here...
Merrick's quick demeanour change suggests that you are not going to be opening a shrink-wrapped book that you haven't paid for. His eyes glance at the Bank, implying maybe you need to get some cash out from there first.
Merrick: Its shut at the moment. You might need to try find another way in. Perhaps if you look at the floor map of the mall carefully, you might get some ideas.
