As an increasing number of people return to work we are seeing a host of operational changes – with layouts being redesigned (especially in break-out areas) and, where possible, passages, hallways and stairs being made one-way. One of the most visible of the micro-effects is a change in the use of common fridges and shared coffee-making facilities. Any laxity on the use of cups and even teaspoons has also gone. The future is going to be a frighteningly new place we are all going to have to get used to.
