It’s the same as her walking over to him and grabbing his arm and saying ‘oh you poor disabled soul let me help you and take you home’
Not quite the same, really. An offer of prayers, however annoying, is only words. Words that can be ignored, brushed off, replied to with whatever emotion (annoyance, pleasure, anger, joy, etc) one wishes. Grabbing someone's arm is a physical encroachment of someone's personal space.
Mind you, in both cases one could give a verbal reply that made it quite clear where one wanted the verbal or physical encroacher to 'get off', as the saying goes. Trouble is, such approaches can leave one a bit dumbfounded by their sheer audacity. And it's upsetting, where upsetting means dismaying, agitating, discomposing, when one is dumbfounded by a stranger's damm cheek.
