Right..Everybody wants fame as the office worker who saw a ghost in their building. lol! Or else as the lying hoaxter that was only in it for the money. Do you have some evidence for this alleged scam? No you don't. You attack an innocent person because they experienced something that conflicts with your personal belief system.
You attack logic because you so desperately want something that doesn't exist to be real...
Except for the fact that these people weren't just paranormal believers trying to find paranormal phenomena. They were just everyday office workers going about their business. No...they didn't consult movies and books to decide what was going on their own office. That's a silly and frankly paranoid claim that has absolutely no evidence to back it up.
And as "everyday people", they are fallible and easily confused/tricked/disoriented and a host of other things... which is why eyewitness accounts are not admissible as a sole source of evidence.
