Q. The other day, when making a purchase in a rather poncy shop, I was taken aback when the assistant stared directly at the keypad while I was entering my PIN. Normally they make a point of rather ostentatiously looking away, but this one made a point of ostentatiously looking at the pad. I could not tell whether this was absent-mindedness, or to make the point that anyone working in the establishment must be above suspicion, or even some sort of double-bluff. I hesitated but then felt I had no option but to key the numbers in with him looking. Since then I have wondered how I might, without being rude, have asked him to look away. —C.B., Aldeburgh, Suffolk A. Perhaps he was innocently day-dreaming.
