THE E.R. BRAKE

I was on the train today and saw the "public" emergency brake. The sign above it read "TO OPEN DOOR FOR EMERGENCY, BREAK GLASS, PULL HANDLE." After I read it, I thought about it for a second...then another second...then another second...then I looked cautiously over my shoulder...looked left...looked right...and with curiosity in my mind, gently touched the glass with my hand to see what kind of glass we'd all be dealing with if an actual emergency took place. I kind of had it in mind that for some reason it would be breakable glass...apparently I watch too many movies...not the case. Turns out it's actual glass...can't fault them there (they have it in CAPS in the directions). OK...so now...if an emergency occurs...where I have to "BREAK GLASS" then "PULL HANDLE", am I just cocking back and breaking this glass with my hand? Not as easy as they make it sound. Cause there's nothing more embarrassing than either A) missing the glass with an overly enthusiastic haymaker that lands on the girl next to the glass or B) punching it as hard as you can and just splintering it (not really sure if "splintering" is even a word but it is now). I feel like the person best equipped to take charge at this time is the one who takes out a hammer from their bag and smashes it. Done. Smashed. Handle is pulled. We're off the train. Every one's safe...and now in the company of someone who's randomly carrying a hammer at 2am.....maybe that was the emergency on the train.
