I have a 60+ yo friend who is never weighed at the doctor's office. When the nurse is escorting her in and says "We're going to room such-and-such, but first stop here and we'll get your weight", she replies in her sweet southern accent (here in NW Ohio), "You go right ahead and weigh yourself honey. I'll be waiting for you in the room. I know how much I weigh and how much I should weigh and being lectured about it won't make any difference."
One of these days she is going to meet a nurse (or doctor) who stands up to her, but not yet!!!!
