Weird encounter in Walmart parking lot

So I went to Walmart this morning and as I was loading the groceries into the car some random old guy walks up behind me. I think he's going to offer to finish putting the groceries in my car or something. Uh, no. He says, "Would you like me to get you some collard greens for your Thanksgiving Dinner?" WHAT?! He either A.) Had some extra collard greens in his car he needed to give away, B.) Thought I needed to eat some vegetables because I'm fat, or C.) Was just plain crazy. I'm going to vote for 'C'.
