Wind Catches Glass Door, Shatters It

This is some security cam footage of a man leaving for his lunch break at *ignores travel posters* what I assume is a sperm bank (donating all morning long leaves you famished!) and the wind catching the glass door on his way out, pushing it all the way back and shattering it. Is that why it’s so cold in here?! Tell somebody to turn the heat up and bring more videos — I’ve seen all these and I hate watching myself anyways.
