Yesterday, I was (very easily) talked into buying the Waterstones book of the month by the bookseller at the till, and eager to reassure me that I was making the right choice, informed me that with the receipt I could get a free hot drink until the end of the month. Not one to leave money on the table, I went back the next day to take advantage of this offer, with a perfectly serviceable hot chocolate and an excuse to sit still and read for a bit. What more could you want?
