How do you say "oops" in Spanish?

From the international relations desk, the staff of a five-star resort hotel in Cancun was undoubtedly shocked and perhaps a little dismayed to learn that they mistook Nobel peace prize winner Rigoberta Menchú for a transient and tried to throw her out of the hotel last week.

Menchú, who is known best for her life's work as a champion of human rights, was wearing her Mayan garb, "the traditional attire of indigenous people in central America," when the Mexican hotel workers mistook her for a bag lady. Oh, and she's also a Unesco goodwill ambassador and Guatemalan presidential candidate.

As if the situation couldn't possibly get any more hilarious, Menchú was at the hotel at the request of Mexican president Felipe Calderón, who invited her to participate in a conference on sanitation and drinking water (apparently she's also a champion of good plumbing. Yeah I don't know).
