Patrons gather inside La Mejor Bakery during the morning rush in San Francisco, Calif., Monday, June 4, 2018.

The bakery makes most of its revenue during the first four hours of daily operations according to Carmen Elias. After that time slot, foot traffic dwindles in numbers and slows in pace. The morning customers, many of them regulars, are a major reason for the bakery remaining open according to Elias.
