DH travels for work a lot (a week away once a month and occasional overnight stays in London for meetings.)
Every single time, without fail, he ends up in a mad rush to leave, and frequently misses his train. Despite my suggestion to, he never packs, or anything else, the night before and instead panics trying to find, or iron, various items of clothing / work stuff / travel documents or whatever. He never charges his hair clippers until he needs them, and there have been several times he has nearly had to leave with a half trimmed head / beard because they haven't been charging for long enough.
AIBU by not doing at least some of these things for him? I don't because I do pretty much everything else in and around the house and think that packing to go away, his personal grooming, and his work stuff, are his responsibility not mine.
(I have ironed a shirt a couple of times as he asked me, and wouldn't have had time to otherwise, but won't generally offer as the chaos is self inflicted!)
