Vending checklist

So I'm Vending for the first time this weekend at a local show. As I'm getting everything together I'm wondering what things I might want that I might be forgetting. I mean it all seems common sense, but maybe I'm missing something.

Displays for animals, heat control, lights, extention cords, table cloth, containers for sold animals, spray bottle of diluted vinegar and paper towel. Trip to bank for 5's and 10's.

What else might I be not thinking of?

Drinks for you, water for animals, markers, pens, paper?

Hand Sanitizer
Munchies and drinks (for you)
Water spray bottle?
Cash box or fanny pack to hold money
If selling hets, paperwork/genetic guarantee
Business cards
Care Sheets (another way to advertise if you put your contact info on them)

Table cloth ! The tables are usually quite ragged
