Every person who walks out of your door should have something in hand to show the next person they see.
Example: I ate at lunch Jimmy John's and I have a magnet and a menu. I also had breakfast at Au Bon Pain – and left with nothing but a napkin. Everyone who dropped by my desk for the rest of the day saw the Jimmy John's stuff, and a few asked me about it.
These visual trigger that starts conversation about you. It doesn't have to be much: A menu, a sample, a catalog, a sicker, a cool shopping bag, a nice box, a lollipop.
(The online equivalent: A white paper, a video to post to Facebook, a coupon to forward, an email subscription.)
