Who was he talking to?

Yesterday evening I happened to be in the lobby of the Ritz Hotel, Madrid's most posh hotel and one of the hotels hosting delegates to the 19th World Petroleum Congress. I walked past a Texan talking on his cell phone and overheard this:

"Thank you for all your help, Your Excellency, and have a good flight home."

Not the sort of thing you eavesdrop on every day.

Just thought I'd share. It invites speculation.

(What was I doing there? Meeting my brother, who was a delegate, to enjoy the wine and food at a Big Oil hospitality suite. It was nice. But all the people I met had first names, not high-ranking titles.)
