#1461: TwinTills

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.
