Call the Authorities
I worked at a small-time aircraft maintenance and supply place. They had opened a new hangar down the road and ordered new toolsets. It was a holiday weekend, and the resident moron was visiting family in the same city as the tool supplier, so they sent him to pick them up.
They bought him a ticket to go down on a Wednesday, and then on Monday—after his vacation—he would rent a box truck and pick up the tool sets. Having this guy pick up the tools was only slightly cheaper and not that much faster than other options.
He rented the truck and picked up the tools the day he got to town. He then proceeded to park the unlocked truck somewhere in the city. He picked up the empty truck on Monday.
He didn’t call the authorities, the company, his supervisor—no one. He just drove the empty truck back. It cost the company over $150K.
