Has anyone ever actually used or seen a valet key? That's the part of the classic ocap intro story that I think is a bit weird; I never heard of one, so I had to first learn what a valet key was, and *then* think about how it applies to delegation/attenuation in ocaps

I never liked the valet key analogy, especially as someone who only briefly owned a 1985 Volvo and now owns 0 cars. I use a hotel key analogy in my talks, which I think is more relatable, but I am still looking for an analogy that doesn't require as much privilege to relate to.

I also think the hotel key isn't as useful for ocaps as a car key, because people often think of a hotel key as being associated with your identity, and a car key isn't.
