However, the first....

Contractors give bids based on projects - after they have seen what they are working with.  Not all kitchen remodels (or whatever the job may be) are the same.  

It is not a fair analogy as a lady's rate is the same for the dingleberried, hasn't-bathed-in-a-year types, the personality-of-a-cinderblock types, the John Q Public types and the Forbes 50/GQ magazine types.  And yet it's HER reviews that will suffer if she can't rim the dingled ass or swing from the chandelier with a cinderblock hanging about her (or rather, lying listless on the bed needing a mirror held to his nose to check for life) - without ever an opportunity to tell her side of the story. John Q Public may be blown away by her but the Forbes 50/GQ type might be less than impressed since she didn't realize that  the napkin is to be placed on her chair rather than on the table when she gets up to powder her nose.

I may be overstepping here, but I think the OP might be saying that it's wise to keep in mind that these interactions take 2 people and as much as the gents try to choose wisely and the ladies try to provide the same level of service to all.... sometimes things just don't work out as one would hope and looking in the mirror (physically and at one's expectations of the encounter) is a good place to start.  

I don't think anyone's advocating for encouraging misrepresentations, but being aware of the part YOU (client) play in the exchange is important.
