Do you use sugar cubes at home?

There's something satisfying about plopping a sugar cube into a cup of coffee and stirring until it breaks up. Of course many argue you should never stir and let the coffee turn from bitter to sweet as you drink it.

The thing is I only ever use sugar cubes when I'm in a coffee shop and never buy them.

What about you?
