I worked at Sears in the mid-70s as a bicycle mechanic. In the winter months, I stocked the toy and sporting goods departments. In the weeks leading up to Christmas, customers would be buying toys faster than we could restock the shelves. It was total chaos on Saturdays. Also worked the year they brought out Pong. We had a display model setup and there would typically be 20-30 people in line waiting to give it a try.
