He expected the assistant to look at him in blank astonishment. However, it was his turn to be surprised, for the woman's eyes immediately lit up and she fetched several bottles which she placed on the counter for Harry to inspect. For once, Harry had to admit defeat. He picked up what seemed to be smallest bottle and discreetly asked the price. He was glad to get away with a mere twenty pounds and he beat a hasty retreat, clutching the precious bottle under his arm. From then on, Harry decided that this little game he had invented might prove to be expensive. The curious bottle, which now adorns the  bookcase in his study, was his first and last purchase of rare cosmetics.
