Emily, you wouldn't last long on the New York Subway. That happens every stop.
We get pet peeves all the time at my job. I work in a wax museum where we get tourists from all over. Every day, I see the bar for human stupidity lowered more and more. How many people here would bring an infant or small child into a "CHAMBER OF HORRORS" (our haunted house section)? What part of "no pictures" and "no touching the actors" is difficult to comprehend? Would you go into a haunted house if you were six months pregnant? Let's not talk about the number of people who ask "Is it REALLY scary??" (It's a CHAMBER of HORRORS!!!)
Sorry, just got off work a few minutes ago and this was the perfect thread to vent.
