Breathing problems
As Adrian made his way out of his house that day, he was accompanied by the oxygen tank that went with him just about everywhere. At his older age, he had issues breathing and even with his hands and legs. So moving around was difficult for him. That being said, he did his best.
He would always try to stay active and not sit too long, so a trip to the waffle house every other day was also a form of exercise for the elderly man. Also, just like Laura, Adrian also liked the staff there and knew Yvonne well. It was a small town after all and a popular place.
