Of course, this is holy shit what a cool way to come off for the employees. But for the Company such events are a way to motivate, adjust staff atmosphere, reduce the "average temperature in the workspace". To make such an event trivial is like to put 50 pictures of food in Instagram.
Even with the stormiest celebration, employees remember such events for a long time. People boast about it, talk about them to friends. These events are being discussed with HR as a characteristic of the working process and mood within the Company.
In general, if you like to know that you are working in a boring and arrogant team — spend your event 10 times in a pirate party style.
