“Nocturnals” are people who sleep in the day to avoid human interaction

I would ask why grocery store employees are forced to work nights and Sundays.

If in Mexico, it’s because the US manufacturers here offer competitive (it’s all relative) pay to operate 24 hours a day, so many folks are night owls who still need to buy things. There are many schools that have night classes for children of night shift factory workers here.
