The flood defences worked perfectly well...................until a security guard thought it would be a good idea to see if they worked well, and opened them up for a gander. YCMIU.
Except it looks like you DID make it up. There were no flood defences in place working perfectly well or otherwise either in the Glucksman or in much of the other UCC infrastructure prior to the 2009 flood. Since then some of the buildings have been retrofitted with flood defences.
Funny how your story was that a security guard rather than say a Professor or student thought it would be a good idea to see if they worked well
