Parens need to stop letting their kid have a tablet or videogame at a restaurant

It is rude for a child to have electronics at a restaurant especially if you can hear it. I get so fed up with parejts that do this. This is why kids shouldn't be going to restaurants if they're just going to be on their electronic device. If this isn't going to stop then I should be able to do the same thing at a restaurant and have it not be considered rude.
