““Then one day our phone rang, and the voice on the other end said, “I need to talk to Mr. Robertson.” “Yeah, that’s me,” I answered. “Are you the one who’s getting duck calls into Walmart stores?” the man asked me. “Yes, that’s me,” I told him. “Son, let me ask you a question,” he said. “How did you get duck calls into the Walmart chain without going through me?” “Well, just who are you?” I asked. “I’m the buyer for Walmart!” he screamed. There was a pause. “One store at a time,” I told him. There was a long pause. “Let me get this right,” he said. “You mean to tell me you’ve been driving around in your pickup truck and convincing our sporting goods departments to buy duck calls without even conferring with me, who’s supposed to be doing the buying for the whole Walmart chain?” “Sir, I didn’t mean to slight you or anything,” I said. “Look, I didn’t even know who you were. Bentonville’s a long way. I’m just trying to survive down here!” He thought about that for a minute, then said, “I’ll tell you what I’m going to do. Anybody who can pull a stunt like that, I’m going to write you a letter authorizing you to do what you’ve been doing.” “Man, I appreciate that,” I told him. “I’m going to authorize you to go into our stores,” he said. “You’ll have that letter from me, and that makes it all aboveboard.” “Hey, I’d appreciate any help you can give me,” I said. So the buyer in Bentonville wrote me a letter and sent it to me. I got the letter and showed it to every store manager I met. They all told me, “Come on in, Mr. Robertson.””
