Sorry to hear that you had an unpleasant stick and puck session at your local rink
Generally, most senior players at stick and puck sessions are always looking to help out those that are new to the sport.
In your case, sounds like it was just some guy on the ice that forgot how it was when he first started and feels empowered by giving players that he does not know a hard time.
Hopefully, the initial experience does not stop you from going back by yourself or with your buds. Congratulations on getting to the ice, hopefully you will have more stick and puck sessions in the days to come.
