Many years ago at the towers, friends of our had 10,000 in cash and a very expensive watch. They came back at night after being out, and safe was open, all there gone. They tried everything to hold the towers responsible but never got anywhere. they felt it was and inside job, someone working there had the was and means to get into the safe. These are people that had the same routine night after night, and were being watched as it happened while they were not there... I would assume its much safer now than then...
Is this first-hand knowledge you have of the people and the actual situation or hearsay? It is a pretty substantial amount and could be very harmful to the place you mentioned if not accurate.
