What became known as the "incident" in your family?

A screaming match in the middle of a popular steakhouse between my sister and mother. Cursing and all.

Story: My sister, mom and I all flew to TN for my cousins wedding. My mom is a borderline candidate for r/raisedbynarcissists, was a pretty bad mom growing up but me and my sister are both mid 20s so we kind of have let it go as we have moved out of the house and started our own lives, mostly to keep peace within the extended family. Ever since my sister had her son (about 1.5 years at the time of the incident) things have been rough. My sister harbors a lot more resentment towards my mom for the past and I have tended to let more things go. Anyways the weekend of the trip my mom was constantly trying to show how "great" of grandma she was, constantly overstepping her boundaries with my sister after being told to back off, she did this in our home state too but was much more pushy having an audience trying to show she was the best grandma and how much my nephew likes her (even though he was clearly attached to his mother at this stage of development)....things were building up a couple days.

The day of the dinner blowout we all went to the zoo and her and my sister had a small squall, mom left the zoo huffy and we all decided to meet up for dinner with the fam as it was our last night in town. My mom and dad (divorced 15 yrs), sister, paternal grandpa(88), maternal grandma (90), and nephew were at the dinner. It was awkward. Barely anyone said anything all dinner, tension was thick. Towards the end my mom made some snide comment and my sister said "if you're going to act like this you are never seeing grandson again"... I dont know who started yelling first but it got nasty quick. We were sitting at a middle table surrounded by other booths and tables and they were screaming, cursing...it was bad. My poor grandparents were just sitting there staring at one another. Eventually, we all left, my mom first...sister ran to the bathroom crying... Dad followed to make sure she was okay... Me and my dad go outside to go get the car to pick up my grandpa who has trouble walking at the door and my mom tries to talk to him about how ridiculous my sister is being...cue my Dad cussing out my mom.. My dad is super soft spoken and I can count the times Ive seen him curse out of anger on one hand so I was like "oh shit, Dad is really mad"...

Its been 10 months, Mom still hasnt seen my nephew or sister and every once and awhile she posts some shit on FB about how her heart is broken, but she brought it on herself. My grandma is constantly trying to guilt me into "making things right" between my sister and mom...as I have any power.
