Tell Him Not to Add Sugar

Living in a first-tier city, there are busy figures everywhere, white-collar workers working hard at their desks. When they are tired from work, they get up and walk to the hot water room. They always like to make a cup of freshly ground coffee. They may not like sweet coffee, but they can't help but add some sugar. Of course, they do it for no other reason than to simply find it interesting. The coffee is very bitter. Someone should add some sugar to make it more mellow and delicious, with endless aftertaste.
