I popped into Tesco the other day to pick up a few things for dinner, and was passing the milk section when I spotted a sign which read 'Milk in isle 3'. As I didn't have a black marker on me I decided to risk the derision of a nearby group of teen shelf stackers by pointing out the error to them and saying 'aisle begins with an A'. This caused a few grunts and looks all round, but they seemed to have got the message.
I was passing the same store the other day and decided to check in on the sign. From afar I could see it had been reprinted, but on close inspection discovered that it now read 'Milk in Asle 3'.
