They indeed do. I spent the first half of my life letting things go, letting by gone's be by gone's, not rocking the boat, but then I realized 99% of people let things go, which really sends the wrong message. If nobody gets called out for their crappy behavior, they think they can get away with it, and they do.
Nowadays, if I see stuff like that, I call them out, in public, so everyone sees it. And guess what, it works 99% of the time, and for those that want to take it to the next level, im game.
