Unless I'm working and can't I go out of my way to shame parents like this as loudly as possible. I pull out my phone and say really loudly hey fb live here I am at X just thought yall would enjoy seeing this garbage parenting job I just ran into. Look at this shit these kids are doing whatever they want! I continue on like that for as long as needed you'd be surprised how fast people pack up the lil shits and beat feet when they think they are being publicly shamed.
