As a disinterested party, I see two causes behind this aggro
1) a student pilot planning to arrive within 20 minutes of the closing time of an airfield
2) an airfield giving permission to a student planning to arrive within 20 minutes of the closing time
When I was a stude (and for some time after), I sometimes ran late (usually through my slowness in checking the aircraft after finding something unexpected, running through the checks etc) and I didn't have the skill or experience to know how to manage it.
It sounds as if both parties carry some of the responsibility to me.
