Unfortunately I think there are always a couple of 'difficult' people that work in public facing roles, whatever the industry but I think the reason people react differently to medical staff is because they are frightened and in a state of anxiety. It doesn't make it right though.
Also I'd expect someone who worked in a care or health setting of whatever nature, would actually care and have kindness as part of their character and when you are faced with the opposite it is upsetting.
