Final answer:
Sherman tends to get impatient with them and doesn't understand that they are likely from a traditional culture and shopping habits.
These enclaves have historically provided support and continuity for immigrants adjusting to the United States, while allowing them to keep their cultures alive in their new country.
Step-by-step explanation:
Sherman has observed behaviors in his grocery store that reflect the pace of shopping and community interaction prevalent among families from ethnic enclaves.
These enclaves, such as Chinatown or Little Italy, formed in many American cities, which allowed immigrants to maintain their culture, language, and traditions while adapting to their new environment.
This communal and unhurried approach to shopping is typical of cultures that value social interaction and community bonds, often contrasting with the individualistic and time-focused nature of mainstream American society.
Therefore, when Sherman notices families taking their time and being communicative in the grocery store, it is likely that they are from ethnic enclaves where such behaviors are part of their shopping experience and community life.
Historically, these enclaves served as a vital source of support for immigrants who faced challenges such as learning a new language, adjusting to American customs, and finding employment.
The creation of ethnic communities provided immigrants with a sense of home, enabling them to keep their cultures alive while they adapted to their new surroundings.
These communities played a significant role in the urbanization of American cities, leading to the emergence of distinct neighborhoods that reflected the diversity of the immigrant population.
