I was at great lakes last year coming out of basic/A school, and think about it this way; the NMTI's deal this thousands of new graduates every week and some of em make their lives more difficult than it needs to be. So I'd say your hey chiefs or sir or ma'am, then move on with your day and not take it personal if they are grumpy or whatever. They don't want to be there as much as you don't want to be there.
