The tiny coffee shop at the railway station I use has installed what looks like a proper kitchen management system to facilitate communication between the till and the barista – in other words, between two people who are standing 3 feet apart. As an inevitable result, confusion reigns, it now takes longer to get your coffee and more incorrect orders are made and wasted. I like computers as much as the next person, but are we too quick to try to eliminate all human to human interaction? After all, the lovely folks in the coffee shop are still more sophisticated information processors than the system that someone has put in to stop them talking to each other.
