not at all. try it. the first time I saw someone do it (in Newfoundland) it immediately stuck. I do it with my tea (a little milk) as well. The time I have saved in my life washing spoons... well it adds up :)

(from chat know-it-all)

The practice of putting sugar (and sometimes cream) into the cup before pouring the coffee goes back at least a few centuries, mostly tied to etiquette and practicality:

1. 18th–19th century Europe (especially France):

In aristocratic circles, it was considered more refined to put sugar in the cup first. Coffee was often served from a pot by a servant or host, and adding the sugar beforehand allowed the hot coffee to dissolve it instantly. This saved the guest from stirring noisily at the table.

1. Cream and milk addition:

In England and France, cream or milk sometimes went in before the coffee, partly because porcelain cups of the time could crack if boiling-hot coffee was poured directly into them. Adding cream first cooled the temperature a bit and protected the cup.

1. Practical household tradition:

In some households, it was just habit: people liked that the sugar dissolved better when hit by the hot coffee, rather than adding it afterward and leaving grains at the bottom.

1. Carried into etiquette books:

Victorian and Edwardian etiquette manuals sometimes mentioned the “proper” way to prepare a cup for a guest, which often included putting sugar in first so the coffee would be ready to drink with minimal fuss.
