I have been shooting some low / more casual steel challenge matches for a couple years at two different gun clubs. Been working hard to up my game, and this season I am shooting in a legit steel challenge league.
Get through all the briefings, join my squad at our first station, and walk to the back of the area (very far back) and take my gun out of the sleeve to put it into my holster. Oh boy, that is obviously a serious mistake. Guy in my squad immediately rolls up on me and explains actually should be DQ'd (correct). I am like great, I drove an hour, my first real match, and I get my butt booted for being stupid before I fire a round. Well thankfully after a well deserved lecture we al moved on and I shot the match.
Bottomline I learned a valuable lesson and it only cost me a little frustration with myself.
