She never asked again.
I said something like this (except it was cookies) to a family that termed themselves to which the parent replied, "I just don't know where she gets that from!"
I'd seen the child eat cookies in a variety of settings and she was an overweight child at that.
Before it got to that point, though, the Dad looked me in the eye and said, "She doesn't want to come here because of what you serve."
