Where's The Common Sense?

Dear Traveling Public: Advice to you while on an Aircraft. Do not try to open the doors in mid-flight, do not lock yourself in the bathroom and refuse to come out, do not yell “I want to kill all…” at any time! And if your religious I’d save the praying for, before or after your flight not during it… What’s wrong with people these days? Just sit down, shut up and enjoy your flight!
