Even something like having an entrepreneur stand and present in front of a group of seated money men. They sit in judgement of him, they are comfy and he stands, they relax and he works and struggles to please them.
Or, when bosses make weird symbolic work demands that don't actually make sense. Sometimes there's the idea that they're just looking out for the product and are wrong about something, but there's also often an element of 'I sense some disturbance in the status hierarchy so I'm going to make you do this task we both know is useless just because I say so to remind you that I can'.
Or 'I'm going to be unreasonable to demonstrate that I can'.
Or 'I'm not going to give this question the think-time it really needs; to demonstrate my superior value I'll save myself five minutes while costing you two days to remind everyone that I'm above you'.
A lot of this is subconscious. The people with the power don't always do it intentionally, thinking "I'm going to signal status today." It's just what feels good and intuitive to them, so they execute these status-signalling behaviours without conscious intent.
