I always have what I carry. Leatherman wave, lighter, small hank of line, bandanna, etc. And of course the clothing I'm wearing can be pressed into use in all sorts of ways.

But because it is rare that I'm ever far from my vehicle my kit remains in the truck. This also eliminates most issues with what is, and what is not, allowed and seen as appropriate in the building. This also makes sorting, maintenance and inventory a lot easier because it can all be done at home.

The stuff I have on me gets me to my vehicle and the vehicle, and/or the stuff inside, gets me to the larger gear.
