An emergency backup generator is only allowed to operate for 200 hours every year and only in the event of an emergency power failure or for routine testing and maintenance.
"Take your child to work" could become a routine practice rather than a single-day annual event, and college students could spend more time watching and helping scientists and scholars at work rather than just listening to their lectures.
Yes, unbeknownst to me, everyone who had signed up for the event (instead of arranging it through a press officer) was sent a video of the routine and had diligently learned their dance steps at home.
