3. Technically an Israeli can even accept bread from a non-Jew and eat it but this causes problems if he is not using disposable utensils (some of which are actually very nice). Per the Yalkut Yosef 448:5:
It is permitted to eat Chometz on a Shabbat which is immediately after Sheviyi Shel Pesach – there is no muktza involved, and you if it was sold to the non-Jew according to Halacha you may eat it on the day of Shabbos immediately after Sheviyi Shel Pesach. However you have to be extra careful not to take the chometz on Sheviyi Shel Pesach since then you will be prohibited to eat it since you have done Baal Yira’eh U’Baal Yimotzei. (Yechave Daat 2 Siman 64, Yabia Omer Orach Chaim 9 Siman 46)
