If the mgmt cannot trust their staff to perform their duties without doing something silly or spectacular on one day - then they cannot trust them on any day.
Plainly, that is nonsense, as they trust them every day.
Therefore, this sounds like a ruse to get the fun 'gig'. I wonder if the management had anticipated this problem when the closure was announced, worked out which of the gigs would be fun and then shared them out accordingly, so that (as far as was possible) everyone got some fun? If they did - then they can be called good management.
