Got chiefed the other day (well it was SMSgt'd, but who cares), walking through a parking lot to my car. The SMSgt was parking his motorcycle, he shut it off and called out "excuse me sir". I walked over to him, knew it was about me having my sleeves pushed up since it was 105 degrees outside. He got off his motorcycle, snapped to the position of attention and saluted, he then very courteously asked me to pull down my sleeves. I pulled them down, he thanked me and told me to have a good day and we parted ways. That is the way NCOs should act not yelling across a chow hall.
