1. I have advertised on my car window that I want to sell my car. I drive us to McDonald's. We get out of the car and an interested buyer sees my ad and says, "How much do you want for your car?" I nod to the buyer and then motion to you, saying, "Talk to my friend here." Then I leave to go inside the restaurant. You work out a deal with the buyer. Am I bound to that deal? Has an agency relationship been created?
