Okay one is in Thames, it’s Saturday morning and you’ve just noticed that the data projector is missing a fairly important element, known as a power cord.
The conference starts in 30 minutes. What does one do? There is no electronics shop open. But there is a Warehouse.
Now the Warehouse does not have any power cords for sale, but it does have an electric jug selling for only $10, which uses the same sort of cord.
The cost of the jug with cord is much the same as buying just the cord elsewhere, so one purchase is quickly made.
