Poached egg whites.

The order taker had no idea how to answer that, so they called me as the manager on duty. I told the gentleman at the window that we could not make that. It is not on the menu, we have no one trained to separate eggs, and we have no way to time it so we wouldn’t know when it was done.

He argued with me (at the drive through window) for maybe ten minutes. Thank goodness we weren’t busy. Finally, he left angry.

Ultimately, if I had an hour to test it out, I might have been able to come up with something edible. That is, if I had stopped managing for an hour to work on his order. But it’s fast food, not a gourmet restaurant.
