What is it about Queenie and her friends that appeals to Samm?

Sammy is foremost sexually attracted to them. Other than that, he enjoys the rebellion aspect that these girls represent. They are girls in skimpy bathing suits. They stand out amongst the tired frumpy customers. Queenie is most desirable to Sam in a sexual and aesthetic way. The girls evoke a feeling that Sam needs to do something different, be somewhere different.
