Breaking norms behavior is a behavior is an act to accept the norms and from the viewpoint of a person the behavior is seem normal Some behavior is not seen normal to some people base on group, community and culture.
Having different beliefs of norms can be difficult and can turn to stereotype or discrimination what people seem normal for others it can be seen weird and not from what they believe is right. In my experiment that I did in the restaurant I learn that having different aspect of understanding how things works can be seen the opposite what others believe is true. Breaking norms behavior can be seen weird.
