Replying to Shattered hockey rink glass? anyone done it?

I had seen glass brake (plexiglass or tempered) just once in 15+ years, and i dont even remember it clearly... i just have a faint memory of it happening.

well until a  couple days ago, when i was able to shatter an entire plane behind the net with a 1 handed swing.  Unintentional of course, i meant to hit the boards, but hit the very bottom of the glass and the whole thing pretty much exploded. it was at the end of the game, and i was pissed cause we just lost in overtime.  Just mens leauge, and thankfully it was the last game of the night at midnight, so no one playing after us got screwed.

but, the rink wants to hit me up for over 500$ to replace it.
Has anyone ever broken the glass or known anyone who has?  Should that just be in the maintenance costs with the team fees i pay every season.  Cause this league jacks the price every new season summer or winter, and from what i see and hear is the most profitable rink in ontario.  LOL oh and im suspended indefinately until its settled, along with me whole team.
