Can you be told off if you are off school grounds?

Answer 1

You can. While school officials have no direct authority away from school, they may still address and advise their students. While you are on school premises, you are subject to school rules. And school rules can be extended to include local community rules, county rules or country rules ( 'the law of the land rules'). So exhibit good manners wherever you are, and you can avoid unpleasant forms of discipline.
