In the gym changing rooms today it was really quite gloomy when I was trying to use my slightly broken locker. The lights in the changing room were all on bar the ones in this row of lockers.
I did try asking the attendant if they were broken and, if not, could they turn them on. To which he responded that they only turn them on after 4:30pm.
It took me fully 30 seconds of 'I guess that seems reasonable' before I got to 'hang on, there aren't ANY windows in here so there's no natural light to worry about'.
Rules is rules, I guess. No-one says they have to make any sense.
