Answer: It makes Mr. Al-Sayed realize how much his son reminds him of himself.
Explanation:
From the passage we learn about Mr. Al-Sayed who runs the Bodega and his son Ahmed, who wants to preserve the family legacy and even skips practicing at school so he could work at the store in Saturdays.
While Mr. Al-Sayed converses with his customers, he remembers how the Bodega was opened and how things were at first compared to the present and this made him remark how he thought his son was so much like him at a younger age.
