Doing it once is OK, doing it multiple times is rude and thus only works with captive audience. She can do it with banker, because bankers' job is to serve customers; she can also do it while shopping because again, its their jobs and they won't kick her out of store for appearing stupid. She might or might not be able to do it with her kids, depending on how they were educated. But asking neighbors to set up hose for watering too many times will likely make them start rejecting the requests (or they'll mysteriously disappear if she approaches them with the hose). Refusing to do boring chores during group activities will likely cause her to stop being invited to those activities, and so on.
