Haha, NYP. 
It's the only school that fines students for not displaying the
student card. All polytechnics and universities have this rule, but
none except NYP will fine the students for breaking this
rule.
And this is not going to be the last time. I've seen it happened a
few times whenever I go past NYP. If any guards or lecturers are
nearby, you will see the cards fly out, immediately hung. Once
gone, off again.
