Queueing in supermarkets is a source of stress that no customer should have inflicted on them.
Today’s invention is a stupidly simple way to alleviate the problem.
Customers can pick up a sign in-store which they attach to the front of their trolley. This enables them to enter a fast aisle in which every trolley is dealt with by two checkout staff.
Their tills communicate to form a single combined bill, so that the escape from the shop is accelerated (by a factor approaching two).
The charge made for this service would be included in one’s bill and would be adjusted so as to control the queue lengths at these double tills.
