Books. I was in London, and...
Which bookshop?
I want to answer "all of them".
Steven King, who wrote many of his 80s books in a drunken stupor, was once asked "how much do you drink, Steven?" King thought the question was exceptionally stupid and answered "all of it."
I missed most of them, I'm sorry to say, but Foyles and Waterstones, and a few along Charing Cross. And the WHSmith at Heathrow.
