The coffee that I hate

What happened to you, Coffee?

You were my favorite thing in the world. There is, well I would say, it WAS my favorite Cafe. They served the best coffee in the city before. But now it taste so weird. Sour! too much things are in the coffee. It is not even clear.

What is going on?

I understand, owner is studying about coffee and trying to make it better, however , Buddy, it tastes horrible. :(

Please do something!
