I got lucky and had a great group of people during MEPS. I also was lucky in that I some how was put towards the front of every line and got out in record time.
Admittedly, my experience in 2019 as an officer candidate was MUCH more palatable than my experience in 2009 enlisting, but a lot of that was just prior service guys and girls working there who recognized that I had played this game before smoothing things out for me. Your mileage may vary.
