I can confirm it is an approach taken by different companies out there. I used to work for this company where every single Friday we would go out for lunch and get tipsy (wine with the food, some digestive liquor shots just at the end, then maybe a mixed drink or a beer at another bar) because we were the only team not allowed to go home early on Friday... for no reason. Mind you, we were some kind of internal IT team and there would be no one to request anything from us, so we never had urgent stuff to do. Back in the office we would enable the "fire extinguisher mode" which meant "only move if there's a fire" and watch silly videos in Youtube, have some coffee with Baileys because why not...
