That's often repeated but not universally true. When the cashier at the grocery store asks me how I'm doing I might say "been better" or something, as you describe for wie geht's, and similarly when I ask them how it is for them they sometimes say something like "ready for the shift to be over." It is very common. But maybe this is demographic or regional - I would not expect older people from the South in the upper class to like this kind of informal response. edit: I would appreciate it if whoever decided to follow me around downvoting all my posts for no apparent reason would provide feedback on what is wrong about my advice regarding idiomatic use of the English language.
