Jesus Christ. No woman I've ever known has this amount of sanitary/menstrual goods stored away. That's insane hoarder levels of stashing.
And they're under the kitchen sink (the place usually reserved for the 'dirty' things like cleaning rags and products). Somewhere where no woman would ever store products that are going to be in close contact with the most sensitive parts of the body.
And, of course, they're owned by a man - someone who has no use for them. Buying pads and tampons evidently gives Jonathan's micropeen funny feelings. The poor shop staff who had to smile and stay polite in the face of this smirking autogynephile who was obviously getting off on the whole situation.
Absolute nutjob.
