Though nobody cared to examine the recent past, a comparison between the murals and photographs taken in 1942 showed that some of the saints had moved, and that Mary Magdalene had lost her shoes.
While common sense says that those who spend work hours popping out to the store for a new pair of shoes or surfing the Web for personal use probably cost employers something in lost productivity, there's no definitive proof that employee "downtime" is any more prevalent than it was a generation ago, when telephone and watercooler banter was in.
