If
A) you're having a man v man at the end of the competition.
And:
B) You see your buddy struggling to pull a mag out from his leather pouch.
And:
C) You have a spare pouch, much better quality, which actually belongs to the aforementioned buddy.
Don't give it back to him, you might end up losing to him in the final by a really small margin which may well have been the other way round had you not given him the pouch...
