What it is about the grocery store checkout that makes some parents just give up correcting their kids? The cashier is NOT a babysitter and letting your child pick things up doesn't help her do her job, especially if they insist on scanning them on their own and you just stand there blinking at the cashier. It's NOT her fault if something gets rung up twice because you thought your kid was SO CUTE trying to "help" the cashier. It's not cute. It's f'n annoying to the cashier and to all the customers waiting in line behind you. It's also not cute when your child screams and flails around on the floor because you wouldn't buy him that candybar. And don't expect the cashier and other patrons to watch them so you can zone out or browse tabloids.
