[Serious] What is something you witnessed that has completely horrified you ?

The worst thing that I think I've witnessed that qualifies is a woman in her late 50s (guessing) choking in a restaurant. After what felt like an eternity but was maybe 30 seconds in reality, she managed to get the piece of food loose, took a huge gulp of air, and said she was OK.

Pretty low grade stuff, right? The part that horrified me was that while she was choking, her 5 yenta friends sat around the table as though nothing was wrong. Even when I asked and said "hey, is she OK?" their response was "yeah, she's fine" and carried on with their BS conversation. It was obvious that this woman was not "fine".

It wasn't until I stood up, pointed at their table, put on the "serious dad voice" and asked "is she choking" a second time so loud that half the restaurant heard me. Finally, they took notice and realized that this woman really was in trouble. I made a spectacle of myself in the process but dammit, she really was choking and I was already running through the obstructed airway/rescue breathing/CPR checklists in my head.
