In this era of increasingly advanced technology, things that we don't expect often appear before our eyes in various ways. This is really heartbreaking for teenagers who are still in school uniforms to sit and gamble casually without anyone being afraid. If you let them continue sitting and gambling, you should be able to give them advice or ask them to leave the place.
Not all places this can happen because of how government regulations handle similar things. In gambling, special rules are also applied for those aged 18 years and over who can place bets.
In this digital era, I think children can gamble easily when they are free to use their smartphones, because when they have their own smartphones, of course they will be able to easily access anything including gambling. Thus, I am not sure if there are still children who still wear school uniforms and then enter physical casinos, because of course they will not be able to enter them because of the age restrictions. But, if they can still visit physical casinos with their school uniforms, then there is a problem with the gambling rules in that place or maybe, the security forces do make it free to be visited by many people including school children.
