In fact, look at the twitter video very slowly...
Where exactly are those doors from the picture? Where are the tables?
Why did the administration make the lame excuse that the tables where placed there temporarily because they were replacing broken tables with functional ones?
Isn’t that an admission that they were responsible? And who in their right minds puts the objects they are carrying through the doors in front of the doors? That makes no bloody sense.
Ergo, somebody is lying to avoid the really ugly fine from the Fire Marshall.
