When it's accidental or someone is apologetic, it never becomes an issue. If someone clearly just doesn't give a shit, like way too many repeated bangs with their board/skis or stab with their poles as we move through the line I find it very hard not to address that. Usually they get the message without having to say much other than a stare or a "REALLY?!?!," although a couple times dudes have tried to buck up, which is hilarious since we both know they're only trying to talk tough in front of their friends.
