When Obama gets to Israel, he'll be staying at the King David hotel, and leaving within 48 hours of the beginning of Passover. Since the hotel staff won't have enough time to prepare for the holiday after he leaves, they've already cleaned the kitchens.
This means Obama & co. will need to order out each night, which will be a headache for the staff who need to make sure he doesn't contaminate anything. Otherwise, any hot hotel food they get will need to be from the Passover menu.
I hope his taster enjoys the bread of affliction.
