I can't imagine it working on a big ticket item. When someone walks out with a TV and the employees walk up and meekly say "plz no steal" it's not always bootlicking like a lot of people on here oft assume but also a way of employees simply covering themselves in case the boss notices and decides to go looking for someone to blame. No-one is worried about losing their job over a hotpocket but giving someone a playstation in an obvious scam is not easy to explain away.
