I worked in a retail/pc repair place about 10 years ago. Boss phoned me one day to say X (customer) device is missing have I seen it? I immediately knew it had been stolen and who by. I was on my own in the shop, 10 minutes before closing and I had been busy for the previous hour so the device was in the front of the shop instead of stored away securely like they normally would be. I was able to find the video within about 30 seconds of getting in and pinpoint the guy. I actually recognised him and was able to tell the police where I saw him somewhat frequently (as I lived nearby too).
Without it, I think all the gingers would have pointed at me rather than me being tired and making a mistake.
