My very first RoA (and first time at HQ) was spent as apprentice corps skivvying in the dishroom and in the meal tent. I had looked forward to a RoA and all the things it supposedly brought, and saw little to none of it. I also saw very, very few of my home twig, which was just a bit unkind since they'd flown from the other side of the world (as had I).
And so proceeded all future RoAs that I was at. I often got lumbered with cleaning the portaloos, which I was glad to do because everyone likes a clean toilet; but it would have been nice to have enjoyed some of what was on offer.
Funny story: one year I was scrubbing out toilets and a "roving minstrel" came to find me and sing me a song. The people who had asked this person to do so was a lovely family that I'd met at Family Camp a little earlier in the year, and they'd sought me out with great diligence because their little boy had really taken a shine to me. I was seriously surprised at this minstrel's visit, came out to see the family, we had a brief chat and I returned to duties. Soon after, that set of toilets blocked up. I'd been so surprised that I'd dropped the toilet brush down the portaloo...!
A less funny story: my home twig were at my last RoA (diligent lot; very big airfares involved) and wanted to spend a little time with me. I was kept too busy and on the very last day was begrudgingly given 1/2hr to spend with them. It was a very cold day and one of them gave me a winter sweater (!) and I gave them a load of materials to take back to the home country, all my Corps notes etc, because I would be leaving myself in a couple of weeks after cleanup.
How mean-spirited, though. Here I am, away from my twig, in the US; my twig from another country come to visit, and I'm not allowed (kept too busy) to see them... three years running. You'd think, half an hour or even an hour, over a week, wouldn't have been too much - but it was, apparently.
