I also had a surprisingly decent experience with MEPS. I was kind of stressing before going in because I had a whole binder of appendix surgery papers from Italy and was thinking I was gonna have to spend $1k+ getting it translated. But they ended up accepting it within a week in Italian!

@b.thomason33 here - if you go in expecting/anticipating a crappy experience, they'll make sure it becomes a reality. But when I was respectful and had a generally good attitude about it, they were more than accommodating on a number of things.
Walked out with zero waivers and hoping it stays that way for OCS/NAMI lol.
