Rivkah said "Shte Adoni." Why did Eliezer say that she said only "Shte"?
R. Bechayei: Due to Musar (he did not want to say that she called him Adoni, respectfully).
One must feed his animals before himself. Why did Rivkah give to Eliezer before to his camels?
Sefer Chasidim 531: Animals come first regarding eating, but people come first regarding drinking - "v'Hishkisa Es ha'Edah v'Es Be'iram" (Bamidbar 20:8).
Chidushei ha'Aderes 156: Here is different, for she was not responsible for the camels.
