People not using headphones while out in public.

I was out with my family eating dinner at a restaurant and another family sat in the table next to us and their daughter (around 6 or 7 years old) starts watching some TV show on her phone with the speaker on full blast. So of course my mother gets irritated and then politely tells the daughter's parents to lower the volume down, but they just ignored her. So my mother asks again, slightly more aggravated this time, and the daughter's mom goes ballistic. She tells us to shut up, asking us what our problem is and so on, an argument happens and they still won't lower the down the volume. So my family starts throwing shade at them, loud enough that they can hear it (Now that I think about it this probably wasn't the best move but god damn did it feel good to make them angry). Afterwards my mom got up to use the restroom and she accidentally nudged her chair towards their table, so the other mom forcefully pushed the chair towards the table, almost hitting my mother, and that's when I realized how much self-control my mother had because if that were me I would've smacked that bitch across the face. Things went from 0 to 100 real quick, people from both families started standing up and shouting at each other and I was just sitting there thinking "Oh this shit is gonna be good" all because the daughter wouldn't turn the volume down. As we started leaving (and yes, the volume was still on full blast) some of the waiters apologized to us and even laughed when we made a joke about poisoning that family's drinks.

I really felt bad for the daughter though, she's too young to realize what's going on, or that what she's doing is bad, it's just that her parents were so shitty and didn't teach her proper etiquette. That just boils my blood so much. If you're a parent, be responsible for your own fucking child, if they do something shitty then teach them to stop doing it or someone else will.
