Dear Shaul ben Abraham,

Great question which many commentaries speak about. I will give you one approach. G-d judges each person on that person's level. For a person with a lot of faith, G-d expects him to display a lot of faith, and he needs to take less action. For someone with less faith, he needs to take more action. If someone with less faith had done what Yosef did, it may have been considered that he didn't do enough. But for Yosef, who had a lot of faith, it was too much.

Some commentaries say the it was the fact that Yosef asked twice "ki im zechartani" -- "if only you will mention me." For Yosef, once would have been enough.
