What you are doing wrong in respect to what? If you ask for A, how would any system know that you actually wanted to ask for B?

Honestly IMO it's more that I ask for A, but don't strongly enough discourage B then I get both A, B and maybe C, generally implemented poorly. The base systems need to have more focus and doubt built in before they'll be truely useful for things aside from a greenfield apps or generating maintainable code.
