There it is again! "easily pulled off all the work".
I notice when the cleaning guys have been in my office over night just to vacuum the carpets. Are you seriously suggesting that someone broke into virtually every office in the building, tore out portions of the walls to allow access to the columns, planted explosives, fixed the walls, painted it to look the exact same, and put all the furniture/paintings/whatever back in place, and the next morning no one noticed?
No one noticed new dry wall?
No one noticed fresh paint?
No one smelled fresh paint? No one used the smell of fresh paint as an excuse to get an extra paid day off work?
No one noticed any of their office equipment out of place?
No one noticed any dust or debris from any of this work?
No one noticed any electrical issues from the wiring that would be needed?
They did this in virtually every office in the building, in three buildings, and they didn't screw it up at all?
Seriously, I do need help building that deck.....All my real friends are completely inept at deck building, and my dad is getting too old!
