the name of the coffee determines when you drink it

So, I've noticed that lately I've been drinking two types of coffee at work. One is Breakfast Blend and the other is House Blend.

Now, I had to wonder this morning why I only drink the Breakfast Blend in the morning and House Blend in the afternoon. Why couldn't I have the House Blend with my breakfast? Just because the Flavia says the coffee should go with breakfast, doesn't mean I have to follow the suggestion, does it?

And also, why don't I drink the Chai Tea more often? It is delicious.
