A border guard has been filmed checking out her social media profile on her phone while checking passports.
The shocking footage shows the woman flicking through posts as she absent-mindedly checks travel documents and other papers.
The immigration official is obviously bored with her job as she rubber-stamps various documents, all the while looking back and forth to her smartphone.
The incriminating video was taken at a border post in the town of Beitbridge in Matabeleland South Province in southern Zimbabwe, though the woman is employed by South Africa.
South Africa's Home Affairs Minister Malusi Gigaba has reportedly ordered the unnamed woman to be disciplined.
