At the commissioning of projects, the former President, in a viral video, was seen wearing a grim look when he scolded the monarchs present at the event.
Speaking in Yoruba language, Obasanjo saluted the Oyo monarchs but ordered them to stand up and greet him.
He said it is essential that they give respect to whom respect is due during a public occasion.
Obasanjo said a monarch must recognise the presence of a governor or president no matter the occasion.
