I didn't drink coffee, but whenever I make a coffee for my father, I'm putting 2 tbsp of sugar, but sometimes, my father is adding 1 tbsp. I think, it is too sweet and I don't like its taste.
Did you mean to write 2 teaspoons instead of tablespoons? If he ends up with a total of 3 tablespoons of sugar in his coffee, all he will taste is the sugar and not coffee.
