Haret Velázquez prepares shrimp and meat skewers with a handmade sauce at a food stand during a regional fair in Delicias, in the northwestern Mexican state of Chihuahua. Velázquez says that he tries to keep his prices affordable for customers, despite higher food costs. He sells the skewers for 80 Mexican pesos ($4) — even at that price, he can't always make a sale.
