This stood out for me:

> On a couple of occasions, I agreed to fill in for the kitchen manager and front of house manager. This was an interesting experience and it worked out well: I got to try doing the job, in a way that was helpful to the business because they needed someone while the normal manager was away, and I got to learn about how it worked, feel the importance of the position for a few weeks, and then I got to step back.

I've often worked on teams where you got to help out your next level lead/manager occasionally. To me it's been helpful in understanding their role and to gain experience without high pressure and risk. Usually also interesting in terms of doing something slightly different for a while (a change is as good as a holiday).

For them it's been a chance to offload some pressure and work to work on something more strategic and a chance to do some mentoring.

This has usually given me good feedback on things that I can do, but would prefer not to have as a main responsibility. I.e. it often informs you about what you don't want to do.
