Two thoughts on comfort items while being delayed:

1. Bring something to do that you wanted to do anyway. This is a psychological head-space to go to, and it flips dead time into non-wasted time. Dip into that book, even if it's only on your phone. Or, for me, rough out a story (I've been tapping out some kids' stories lately, and kids actually seem to like them.)

2. Bring as much hand sanitizer as you can get away with. With wet wipes, rough paper towels, TP, you can really freshen yourself up and feel a little more human. It's the ultimate multipurpose "instant shower." Some people don't like the glycerin residue but note that it's water soluble. You can even use the stuff on your hair. I make full use of this when camping rough for a couple of days and then popping into a nice little restaurant or meeting friends enroute.
