Drives me up the wall on my way home from work through a trading estate..
Open plan office buildings with every single light in the ceiling on and not a soul in sight.
Maybe the cleaners are in there but on every floor everything is glowing like a Christmas tree.
Thing is they can have enough lighting for cleaning and security even if they switch off half the lights. I don't understand this about shops like Primark, which leave ALL the lights even the spotlights. If they are putting out stock during the nights then can have enough lighting by switching off the spotlights and keeping the overheads on. That's what we did in IKEA when I worked there.
