Time spent in bookshop can be most enjoyable, whether you are a book lover or merely there to buy a book as a present. Whatever the reason, you can soon become totally unaware of your surroundings. You soon become absorbed in some books, and usually it is only much later that you realize you have spent far too much time there and must dash off to keep some forgotten appointments—without buying a book, of course. This opportunity to escape the realities of everyday life is, I think, the main attraction of a bookshop. If it is a good shop, no assistant will approach you with the inevitable greeting:"Can I help you, sir?" You needn’ t buy anything you don’t want. In a good bookshop, an assistant should remain in the background until you have finished looking through the books. Then, and only then, are his services necessary. You have to be careful not to be attracted by the variety of books in a bookshop. It is very easy to enter the shop looking for a book on ancient coins and to come out carrying a copy of the latest best-selling novel and perhaps a book about house decoration—something which had only vaguely interested you up until then. This volume on the subject, however, happened to be so well illustrated and the part of the text you read proved so interesting that you just had to buy. Booksellers must be both long-suffering and tolerant.
