Why using "Group By"

CUSTOMER_TABLE Isn't it clear that I want to get the number of rows per city, so why is it necessary to add:
CUSTOMER_CITY I mean to say that those added lines didn't give more information, and any resonable person (or a good sql parser...) could have understand what I really want at the first sql.
