It’s a small thing, but a final touch.
You order a coffee, but you get a little extra on the side.
That’s a sweet thing I like about cafés in New Zealand.
Your order of coffee would come with a Jaffa (orange coated chocolate ball), a chocolate fish (chocolate covered marshmallow fish) or a small plain marshmallow.
This should be applied to many things in life.
Under promise but over deliver.
