DENVER -- Across the country Thursday, restaurants and other businesses closed in response to the nationwide "A Day without Immigrants" protest.
In Denver, some of the restaurants that shuttered included Biju's Little Curry, Palenque and Marie Empanada.
"I never want to forget I am an immigrant and that's why I made the decision to close the doors today," said Lorena Cantarovici, the owner who is from Argentina.
At Skinner Middle School, many parents were called by their children after reports the cafeteria workers walked off.
As a result, orders of Burger King and McDonald's could be seen being brought in by the dozens -- bothering some parents.
"Nobody knew about it. You got your kids calling you in the middle of the day saying there is no food. So yeah, it's an inconvenience," Nolan Mitchell said.
Officials with Denver Public Schools confirmed the cafeteria workers returned in time to serve the hot lunches.
At Escuela Tlatelolco, a school at West 29th Avenue and Federal Boulevard, students protested in the streets although the story might be the number of students who missed class.
Of the 145 students who attend the school, only 40 were in class Thursday.
DPS said attendance was estimated to be about 5 percent less Thursday than Wednesday.
