This is the tricky part how one defines being humble.

Let's take restaurant housekeeping and stewarding for example. Everyone, especially those wearing suits and vest as Front of House and Managers can say that washing, cleaning, sweeping and mopping are humbling roles.

However, none of them (the supervisors or managers) are wiling to do it daily in the restaurant. They are just so thankful someone else will be doing it and get stuck at the role for a long time.

To them, what's important is that the restaurant operations run smoothly and it is not them who have to do the cleaning tasks.
