I've made it a habit to make single-take videos of any transaction/interaction worth more than I'm willing to eat the cost of. Along with buying a roll of tamper evident tape. Mailing in a warranty claim? Document it's condition and problems on video and seal it up in my car then hand it over to FedEx in a single take. Amazon orders? Start the video with the box still sealed and showing the shipping label, then open and document condition and serials.

It's super low effort these days, and the single take is (IMHO) more important than perfect framing or audio as long as identifying details are legible at some point.
