What is Something Considered Socially Acceptable that You Can't Stand?

Often times people say that autistic individuals should learn to mask to fit in better with society but as someone on the spectrum I find certain things that are considered normal and acceptable within society are things I can't stand.

The big one for me is kids running around screaming in stores and restaurants while the parents do nothing because, "That's just kids being kids."

I don't have any idea why that's considered acceptable especially when autistic meltdowns aren't considered acceptable.
