Napkins (also in various and multiple pockets, I always have napkins).
Plasticware, chopsticks, condiment packets (whatever is extra from carry-out)
OBD2 Bluetooth code reader
Headlamp
Medicine (prescription and OTC)
Gum
Eyeglasses screwdriver
Charging cords (I have a couple of large batteries, but I don’t always carry those)
Pen
Jersey gloves
Ear plugs, cheap and individually wrapped, because I ride a motorcycle and will hand them out, and my son is a musician and has friends over and I make it rain earplugs.
I chose a purse over a backpack.
