I encountered this sentiment most of all - 40 year old dads who were suddenly stuck at home with the wife and kids, working from an improvised home office.
When I asked about returning to the office, most of them were clearly looking forward to it, with a sentiment of "Of course working from home is less efficient and comfortable, what do you mean?".
It was quite a surprise for me, who had finally gotten away from the noisy open-plan offices and meetings where everyone shouted at each other until the loudest person "won".
