Someone said that they think putting sugar in coffee is wimpy.
It depends on how large the cup of coffee is, and how much sugar you
put in. At a coffee house, a large cup with only one sugar packet -
the taste of sugar really isn't noticeable; because of the ratio of
coffee ml to sugar ml.
I can agree with you when a small sized cup with three or four packets of sugar can be considered "wimpy"; because there's so much
sugar in such a small cup, it kills the taste and aroma of coffee.

For me, it depends on how hyper that I need to get.
