iPads at dinner

I am a to each their own kind of person. We don’t do iPads at dinner out, but I get why people do. Sitters are expensive parents want a dinner out and a break. Tonight we were at dinner and the table behind my family of 5 had their young kids on two iPads, but no headphones. It was so loud. I didn’t want to judge or complain, but really? We had to yell to hear each other. The servers looked uncomfortable, but clear vacation spot where they are not going to do anything if people are not complaining. I think they realized they were disrupting so they turned it down, but then the child started screaming so they turned it back up. Is there just a point where maybe don’t go out if your child can’t sit and can’t use headphones? Do we all need to hear it? Do the parents just not hear it anymore?
