Queen Letizia of Spain managed to side-step an awkward moment as she carried out a public engagement in Madrid on Monday.
King Felipe's wife, 48, arrived at the Clara Campoamor tribute at the Congress of Deputies, but there appeared to be no one there to greet her at the entrance immediately.

WATCH: Queen Letizia left waiting after protocol failure
According to El Mundo, Queen Letizia passed the time by waving and talking to the press gathered outside, before an authority quickly came to receive her at the door.
Usually, protocol dictates that a host should greet a member of the royal family upon arrival at a public engagement.
But the royal didn't appear to be fazed as she posed for a photocall and then proceeded to preside over the tribute at Congress.
Clara Campoamor was a Spanish politician and feminist best known for her advocacy for women's rights and suffrage during the writing of the Spanish Constitution of 1931.

"At this painful time, we would like to convey to you our deepest condolences on behalf of the Spanish Government and the people and all our closeness and support.
"We will never forget the occasions we were able to share with him and the legacy of service and dedication to the Crown and the United Kingdom that he always carried out at your side. Our thoughts and prayers are with Your Majesty and the whole family. With all our love and affection, Felipe, Letizia."
