I just did, like 15 minutes ago. He was inspecting what was supposed to be the best hospital in the country. He came almost without notice, so it was quite incidental.
Then some of my co-workers were discussing about the President coming, which they were not sure about. I told them that I saw him, and they went crazy, saying it was damn cool and told me to describe him in detail.
Funny I felt lukewarm about this.
Anyway, have you seen your nation leader in person? And how?
