Code:
function event_say(e)
if(e.message:findi("hail")) then
e.self:Say("Greetings, fine friend! I bet you are in need of some fine tonics. Feeling a little low? Take a drink of my fine Zap Doodle Tonic. It will give you the energy of five hill giants! You are in luck, my friend! I have it on sale today, and today only. Matter of fact, the sale ends in five minutes or five footsteps, whichever comes first. So don't be down... get an upside-down frown with my Zap Doodle Tonic! All sales are final.");
