You don't have to measure anything because each sugar cube is exactly one teaspoon of sugar. You don't tear open a package and contribute to paper waste and garbage.
And the coolest thing of all is that sugar cubes dissolve in your coffee. One minute it's a cube. The next it's gone.
Sugar cubes used to be used in diners and restaurants when I was a kid. Not anymore. Now it's just the sugar packets because people didn't like the idea of using a sugar cube that could have been touched by a stranger's hand.
