"Yourself" is a reflexive pronoun, used here (incorrectly) as the subject of a sentence, but should be the object for an action you perform on, erm, yourself, eg. "Eggs and bacon for the lady, and what will you be having for yourself?" And using the verb construct "be having" is more of an affectation than an error. "Be having" is best used to imply the future, but "have" is best used for immediate action in the present, eg. "I'll have the eggs today and I'll be having the bacon tomorrow." OTOH, I use that "be verbing" construct all the time in tech support, eg. Them: "The instruction manual says to do this." Me: "Don't be reading that!"; Them: "Everything disappears when I rm -r" Me: "Don't be doing that!"
