I asked someone besides me why did they allow this boy's to come in with their uniforms and gamble, he said did they put any restrictions that younger ones are not allowed to gamble. I said but it's not normal, I replied him what if this are your kids would you be happy seeing them gambling with their uniforms on them. So what do you guys think about this situation at hand now.
It's more on the influence of gambling nowadays as let's say like 10-20 years ago wherein there is no online games and the youth can even get to traditional base casinos as they are very strict as far as the age of people entering their premises.
But it's obvious that we don't want our youth or even our kids to gamble at the early age. In your example, if the government does allow gambling but restricted 21 and below then it will be illegal for betting shop to allow this kids are they are in uniform. Maybe they are just fly by night betting shop, but if they are regulated by the government then this is a serious offense and should be reported to the police.
