She knew exactly what she was doing, she knew she would only face a £50 fine and said stuff the authority's.
That fine should be a minimum £1000 for each week for each child and that should stomp these mindless parents flouting the rules, what would your boss do/say if you asked for a week off, he said no and you took it anyway.
It doesnt matter squat if it's the end of the year and nothing will be done, rules are rules and are there for a reason, The fine should have been a lot bigger.
