What metaphors are used in The Latin Deli: An Ars Poetica by Judith Ortiz Cofer?

The final images of the poem describe the extreme pathos of the exiles' situation. An old man, symbolizing all old men who are exiles, must have the ham and cheese sandwich from this deli, even though he could buy a less expensive sandwich elsewhere. The proprietress, in her role as patron saint of the exiles, attempts to satisfy this need by making the sandwich in the way that the man remembers it being made in his own country, "slicing jamon y queso and wrapping it in wax paper/ tied with string: plain ham and cheese/ that would cost less at the A&P. . ." The man's "hunger" is an appropriate metaphor, and the physical nourishment with which the deli supplies him only keeps his real hunger for his homeland alive.
