There's no time to waste, so they down it in one, Italian-style gulp.
Sagittarians like a cup of coffee on their own first thing in the morning.
To them, there is no better time than first thing in the morning to assess the day ahead and get their battle gear ready.
Capricorns like the variety of coffee flavors. They're hooked on the taste of coffee more than the caffeine.

Like their gloomy disposition, they like their coffee black.
