Queen/King for the day

I was recently talking with a friend of mine, who has a financial planning business, about ways we help others feel valued and special. One great tip she had was called "Queen/King for the Day". Some schools do this activity too, where each child gets one day out of the academic year to be King or Queen. This can involve any activity that makes them feel special, i.e. getting to wear a crown or bringing them water in a special glass when they ask for it. For my friend's team members, they each get one day per year to be 'Queen/King for the day'. She takes them out to lunch at a place of their choosing, they get a special plaque on their desk and various other things on their special day. You can do this activity as a unique way to make employees or loved ones feel special and valued. I'd love to hear how it goes.
