What gets me, is they have these parents going well my 11 year upwards child didn't make the correlation between buying it with real world money!
Get the fuck out of here, your kid knows full well they're spending money. Money isn't a foreign concept to them at that age.
The younger kids being blameless is fair enough, they don't understand what's happening every time they click that "het crystals!" Or whatever shit it is.
You learned about what money is before the "introduction to money" ceremony at your 18th birthday? What backwards ass place do you come from?
