What is the Summary of A Supermarket in California by Allen Ginsberg?

A Supermarket in California is a lyric poem written by Allen Ginsberg in 1955. As with many of his poems, Ginsberg ultimately criticizes modern America; he uses his poetic idol, Walt Whitman, as a connection to the past in order to contrast the two societies. Themes of homosexuality, capitalism, and conformity dominate the poem as Ginsberg takes a seemingly typical trip to the supermarket.
