I normally get gas on the way to work. Gas is significantly cheaper along the highway than it is in Chapel Hill. I even know which gas station has the cheapest gas. There’s a billboard with their price so I can compare it to other stations. I got off the highway on my way home to get gas. I had been on the phone, but I hung up to pump my gas. I dialed my call and got back on the highway the way I normally go. It was 13 miles before I realized that I was going the wrong way and I had to turn around. I wound up driving an extra 30 miles on my way home on top of my normal 53 miles.
