Having had way too much coffee during what I laughingly described as my working day, I found it hard to sleep last night. The upside of this insomnia though is that the following idea took hold.
Today’s invention is a coffee machine which contains a clock. Anyone ordering a double espresso after 3pm would be given a warning message: “Are you sure?”
This machine could also come supplied with a proper, ie plain ceramic, mug for every one of its users. They would be encouraged to draw a mark on the base -which would allow them to be identified by a small camera in the machine’s dispense chute. The system could then issue healthy guidance like “Hello John, how about some green tea, since you’ve had five coffees today?”
