How would you react if someone showed up to a uniform inspection with a ribbon rack like this?

NOT in my outfit!

Seeing this could cause permanent internal damage to a Senior Chief!! ha ha

If time allows, send them to the Exchange for a ribbon bar. Otherwise, if regulations permit, ask them to remove the ribbons until they can get the necessary ribbon bar. Counsel whoever should have made sure his stuff was squared away long before inspection time.

Alternatively use this emergency procedure: use two single-ribbon bars and three ribbons. Remove ribbon bars from three ribbons. Arrange ribbons in proper order of precedence. Insert a single ribbon bar half way into the center ribbon, insert another single-ribbon bar into the other end of the center ribbon. Add one ribbon on each end of the center ribbon. Add to uniform. Carefully add the fourth ribbon centered above the row of three. It isn't pretty, but it's better than the illustration.

Sloppy sailor

Even a boot trainee should know better !

I'd splash that person full of holy water screaming at the top of my lungs "the power Christ compels the" "the power of christ compells the"!!!!!

Damned Boatswainmates

Imagining some kind of formation on the ship or before a ceremony. I'd probably just look over at the Medical Officer (usually medical and chaplains tag team, at least the commands I've been at) and kinda do the wide-eyed-nod in that sailor's direction. If I've seen it, their Chief has seen it. And every Command Master Chief I've been with can tell when his/her Chiefs are getting red-faced and blowing steam. Some sixth sense thing or something. But then I have found that sometimes when Chaps pulls a sailor aside to gently but quickly fix something before Chief can, sailor is appreciative to Chaps and Chief is appreciative to Chaps. Sometimes I can make life go a little smoother for everybody by helping here and there behind the scenes, as it were.
By the way, when pulling SMs aside, I recall when I was a young, new, college Midshipman in NROTC. I knew the 6-steps-away-and-salute rule. But this USMC Major in our command was just so imposing! He was a competitor on American Gladiators (got the sticks broken over his head by Laser, it's on youtube) and he flew one of the Marine helicopters that got Scott O'Grady out of Bosnia, and he was on the USMC recruiting commercial with the chessboard and the lightning striking the knight that turns him into a Marine (also on youtube, 80's recruiting vids), and he was studying to become a physician....anyway, I saluted and gave the greeting of the day, waaayyyy before six steps. Like, across and down the street. "Midshipman, come here." Puts his arm around my shoulder, "You're not in trouble. I'm just giving some pointers," and goes about correcting and explaining. Really meant alot that the literal poster-boy for the Marine Corps would take time out of his day to kindly mentor an 18 year old MIDN. I'm not saying I'm anywhere near his awesomeness level, but the quiet mentoring is something I've tried to copy as I've aged.

Seems like his command let him down.

May God welcome you to Heaven. Because I am going to kill you ..... jk
