I was perusing the shaving aisle at Target, and a little elderly lady came up and asked the nearest clerk if they had single-edged razor blades. The clerk had NO clue what she was talking about; I didn't see any on the shelves, so I intervened and told her that I'd seen them at the nearest drug store. She told me her husband had recently decided to start using a SE razor, and she had no idea where to get the blades for him. She was surprised someone my age would know what they were, much less where to find them.
