Translation of cordialmente

Yesterday, I heard a very good example to explain my point: On their journey more than ten years ago, the presidential couple Mr. and Mrs. Clinton visited Egypt. They were welcomed by the president.
The ride took us through mountainous areas, covered with dark green forest, with so many curves that I got sick. I wanted to vomit but I held myself back, as there were so many other next to me.
Usually I do not care too much about not getting change, but when you pay a 3 dollar ride with 50 dollars, you do actually expect change. We stood there for a while and neither of us knew what to do.
