All the above!
Here’s some logistics lessons I’ve learned. Most of my experience is scribing at the VA Horse Center, so you’re more familiar with your surroundings than I was with mine (had never shown there, only volunteered). IMO the more prepared and comfortable I am, the better I can concentrate on supporting the judge.
Dress comfortably, but nicely. The first time I scribed I wore my “best” barn work clothes, then felt a bit awkward next to the well-dressed judge. The next time, I dressed a bit “too” nicely, to include fancy-ish shoes, so of course it rained all day and at times poured buckets, which flooded the end of the arena we were in. The judging booth was like a little island in the sea. There, l learned to wear footwear appropriate for wading through ankle deep water. Take a rain jacket, shawl or blanket in any weather other than high summer. Never know. My rainy day experience was in the summer but after getting wet (and not taking an umbrella because of horses, of course) I was chilly once judging resumed.
I now also pack a towel and alligator clips, after the experience where I sat in a passenger seat all day and as the afternoon progressed, the sun beat down on the passenger side like Dr. Evil’s death ray… I was miserable! I had something I draped over the open door then closed the door on it, but those evil rays snaked into and around every opening, and could have been solved with a judicial placement of alligator clips, the large kind. Lesson learned.
Also, if you don’t know already, learn where the closest restroom is. Yet another experience… we had a no show so I had about 6 min, decided to take a quick break, “official” restrooms were some distance away and I reasoned that there had to be something closer to accommodate competitors. There was, but it wasn’t apparent, time was ticking and I got a little desperate, finally found someone braiding who looked like they might know, and they did, and I returned with plenty of time. But I’d have avoided that little bit of stress with a simple reconnaissance before-hand.
Whatever drinks and snacks you may prefer. IMO VHC is generous to its volunteers, but as a scribe you’re still captive to a car or booth for possibly several hours at a time. And be careful of AM coffee consumption, if that’s your thing.
Arrive early, review the order of go and corresponding tests required and supplied, and ensure you have extra copies “just in case”. Have that ready well before the judging starts.
Finally, not required I think but nice to do, is after you have tests ready/your things ready to go, if you’re in a booth it’s nice to tidy it and arrange things so the judge can arrive and get right to work. I once arrived at a booth/trailer that looked like it had been used for storage for some time, and hadn’t been kept very organized. I took a few minutes to arrange random stuff neatly out of the way, swept the floor and surfaces, got the judge’s area ready and made sure they had the (most) comfy folding chair of those available. The judge actually noted that I’d done this and said a quick “wow, thanks” before getting down to business, so that made me feel good.
I really love scribing. It’s a personal challenge for me to get down as much as possible of the judges comments, especially if they say more than “halt not square” or “fairly straight”. Some don’t, but some do!
