Arbitrary Pet Peeve

When people who are waiting to cross the street at a crosswalk and they KEEP PUSHING THE DAMN BUTTON!!! Beep-beep Beep-beep Beep-beep Beep-beep. I just want to shout at them, "STOP IT!!! it won't make the light change any faster!!! ARGH!!!" *eye roll and huge exasperated sigh* But I keep my mouth shut, because even though it drives me crazy, they won't care and will probably keep pushing it anyway.
