Magdalena Rivas, a large woman with violet-tinted hair, scarlet nails and a Bible by her side, has just finished her shift at the funeral parlour where she puts make-up on the dead. Now she is sitting in her favourite lunch venue: the Pollo Campero on Guatemala City’s Seventh Avenue.

She has been going to the Central American fast-food chain about twice a week for decades and on this Sunday afternoon she is savouring the last of her Super Campero combo – three pieces of fried chicken in breadcrumbs, a side order of coleslaw, French fries, a bread roll and a fizzy drink.
