yeah, i don't mind that. those type of guys will get there's eventually. i have 2 at my gym like that, an older gentleman in his late 40's that seems to really enjoy dominating white belts like myself and another younger smaller guy that puts on clinics and cranks holds so you feel it the next day. guess what, they're both buddies too and they offer no help to new guys. never telling them what they did wrong, what they can improve on, nothing.
i ain't worried though, they're the minority in my gym. i will use the both of them as examples of what not to be during my progression. keep my ego checked, stay humble, and help others along the way.
