Emergency Button in Toilet Stall

I'm not sure if I've ever posted a emergency button picture from within a toilet stall before? If so, here's another one. I've always wondered what happens when you press the button? Does the entire staff run into the stall to make sure you haven't fallen in? Do they send in a robot with a try of toilet related items? Does the entire bathroom lights go red and a buzzer goes off as the toilet starts to drop into the floor and converts into an emergency bomb shelter? And if you press it accidentily or on purpose, would you be fined or arrested for putting the scare on the staff? I'm so curious...... yes, another iPhone picture.......
