peeing in water bottles is pretty common for delivery drivers. ask around. yes, it sucks.
Ultimately, what defines advertising is payment and control.
hot take: facebook, google, and youtube are all ADVERTISERS. That's how they make their money.
it should be illegal to advertise to children.
I agree it should be illegal to advertise to children, but honestly children are the #1 source of revenue for a lot of companies. Kids see ads on Nickelodeon & Cartoon Network and then beg their parents for whatever dumb product they saw on TV. Then parents say "okay I will buy it for you" because they love their children and want them to stop crying about dumb shit.
It's pretty insidious how companies exploit parental love for their own gain.
Oh and don't forget mobile apps. Kids will play stupid mobile apps and every few minutes they will see an ad for another game.
