A young lady had started working at a pharmacy and, after the first month, was given a performance review. Her boss was very happy with her work in general but was particularly impressed with the high turnover of condoms she had achieved, compared to the other employees. He asked her the secret of her success.

"They come in packs of 3, 12 or 60" she explained. "If someone comes in for condoms, I ask them if they want small, medium or large and they always say large so I sell them a pack of 60".
