Drop a line to the owners of the rink. Tell them that you'd be spreading the word about the place if a-holes like that were not there.... Or, next time, just give him a big clean hit and drop his ass.... that will shut him up, and if not do it again till he gets the point.... Basically he is a playground bully with a small penis, cheating wife, miserable boss, all three, whatever.... "his" rink is the only place he has any control over and needs a good bitchslap. OR, take him out and get a beer.... much easier to make friends out of enemies, ya know.
