Funny enough, it's already causing a lot of distractions in secondary schools, and the school management isn't doing anything about it. Unlike during our time, when the school was very strict, now most of them, mostly private schools, don't really care about this; they don't want to offend anyone that might lead to parents withdrawing their kids out of school. So they ignored most of these things.
That's private school at its best: they'd rather allow the students to rot out of fear of losing them than take proper actions that can sharpen their lives for the better.
