OK, not really an adventure but -
I could spend all my time telling people that they need to tie their laces tighter, or need smaller skates. I wish we had a great big sign by the rental counter that explained how important that is.
Virtually everyone who has trouble staying up fits those parameters, even among beginners.
I did some of that, for the worst cases. But it is pretty boring to do.
It's clear that from a business perspective, the rink is best off if we stay by the doors instead of skating, and make sure no one comes in who isn't wearing the wrist band that shows they paid.
So far no one has seriously hurt themselves.
