Regarding the line cutters, I don't know how people manage not to beat the crap out of rude people. If someone rudely pushed past me after I told them I wasn't putting up with their shit, there would be a fight.
When I was at the zoo and the aquarium on vacation, people would be rudely pushing and shoving to get pictures of the animals, with no regard for the fact that everyone else was trying to get pictures of the animals. After a while I got sick of it, and would push back.
Like I said, at one point I decided to get rude myself and hold a spot for my son so he could get close enough to get pictures. People kept getting in front of him and preventing him from getting to me, I held a spot and reached for him, cutting off people from getting in front of him ignoring the dirty looks I got.
I started saying things like, "It'd be a lot easier to take pictures if people could say excuse me, but nobody seems to know that friggin word!" and "Jeez, I hate rude people! They just bump right into you like you're not even there!" I said these things loud enough, that I hope the people they were directed at heard them.
As unfortunate as it is, sometimes you gotta fight fire with fire. No matter where you go, no matter what you do, there will always be assholes who don't care about anybody, but themselves, and fuck you if you have a problem with it.
