If he wanted to have a quiet meal, he should have gone to an actual restaurant, not a fast-food joint. Apparently he could afford to.
He didn’t say he required a quiet meal, he complained, and took appropriate action, against an assault on his senses. There’s a difference.
He could have had a short lunch time. Real sit down restaurants have their fair share of bratty kids. I think (probably wrong) it was an Olive Garden that banned the little monsters last year. Just saw this one banning noisy kids - http://www.foxnews.com/leisure/2014/07/31/ca-restaurant-effectively-bans-kids-with-sign/
I’m on a very frugal budget but I would have brought every pie in the joint and told the mother and her potty mouthed kid exactly why I was doing it. We would have to scratch bread and milk off the grocery list for the next two months, but it would soooo be worth it.
