Ethanol and gasoline don't separate when you let the mixture sit. If they did there would be a big problem at gas stations. There are a few different lab tests to to determine the ethanol percentage, a dealer would not be equipped to perform any of them. I would stay away from that dealers service department, if possible, they are clueless.

Again, it seems to me you got a bit of water in there. Water can cause the ethanol to separate out from the gasoline. Since you refilled and all is fine, don't worry about it.
