Argos is a well-known British chain of shops that sells many kinds of goods for the home — kettles, toys, furniture, and the like. The classic way, which the name still calls up, is this: you look in a catalogue, take a product number, pay at a desk, and wait while someone brings the box from a warehouse at the back. You do not wander the aisles the way you do in a supermarket. Though actually the big paper catalogue is mostly gone now, and much of the ordering is online, the click-and-wait habit is still what British people picture. This entry is the store, not the old Greek city and not Odysseus’s dog.
