It says "the men on this level are not bad looking, earn $20,000 per year, can tolerate kids and will do housework occasionally".

The males are there of their own free will; they want to be chosen as husbands. In using the store there is just one rule. It goes like this - the husband store exists of four levels. Everyone entering it proceeds upwards level by level from the ground floor once they leave a particular floor they may not choose one of the men on that floor only one of those from the floors above.

A husband seeker enters the building and sees a notice on the first level. There are no charges for selecting one of the males in the husband store. Those seeking a husband can go to it and select their ideal partner. Have you heard the joke about the husband store. The husband seeker proceeds to the next level.

In other words having rejected the available males on level one the husband seeker on reaching level two cannot change her mind and decide to choose one of them.
