You say that like teens have the willpower and emotional control to do any of this. Those teens will absolutely walk off jobs because somebody looked at them funny, and now they have beef. And it won't be until after they get into a fist fight and get fired that they'll realise that was a mistake. Teenagers aren't methodical plotting analysts that understand what they're doing. Their body is going through hormonal changes, and it affects them all differently. There is no plan with them. The plan is they saw another kid give them the finger and now they're about to come to blows. The fact that they're wearing work uniforms while doing it isn't part of the plan.
