Once people have finished watching the video, talk to them. "So, what did you think?" is a good opener. Now is the perfect time to answer questions they have, give tips on veg eating, and let them know they can help stop the cruelty they have just witnessed. Make sure they know that changing their diets is not an all-or-nothing proposition; even cutting back on meat consumption can help.
Give every person who watches the video a copy of our "Vegetarian Starter Guide" with the dollar bill inside. Also ask people to write their email addresses on the sign-up sheet so they can receive helpful resources on veg eating. After the event is over, take a photo of the sign-up sheet and email it to MikaelN@MercyForAnimals.org so we can send out those resources.
