On Friday morning, a woman walked up to our booth. She said: "You guys look like you know what you're doing. Do you have a bandaid?"
And I replied: "Yes, let me get our first aid kit."
As it happened, I had needed a bandaid myself earlier that morning and had opened the brand-new kit, thinking to myself "Good thing, because if there was an actual emergency, I sure wouldn't want to be pulling the plastic off in a rush."
This wasn't an emergency either, but it felt good to a) be recognized as a place where we would have the necessary supplies, and b) to actually have them, know exactly where they are, and be able to quickly offer a variety of bandage choices to the con-goer—who, like many, had given herself a blister walking the show floor!
Making a TODO list for your next convention? Whether you're an attendee or an exhibitor or a special guest or anyone else: get a small first aid kit. Hopefully you'll never need it!
