According to Halacha, Jews should wait at least 1 hour (according to some ashkenazi Poskim) or 6 hours (according to most Sephardic poskim) after eating Hard cheese before eating meat. Since chicken mixed with dairy is only forbidden Derabbanan, may they eat it before their usual waiting period is over after eating hard cheese (so long as they have cleaned their mouth first)?

By Halacha, besamim isn’t used for havdalah when Motzai Shabbat is Yom tov. However, if there is a wedding, bar mitzvah, Brit milah, etc. being held the day after Shabbat, does similar reasoning apply To the individual and/or their immediate family and is besamim not used by them?
