Well apparently, you seem to think that you were at the Last Supper.  And I suppose that you have read and done research on how public meals were served in both Palestine and throughout the Mediterranean area [during the Hellenistic period].  This also takes into account as to WHO was permitted to attend these meals.

We [biblical/church historians] have much evidence for participation of Jewish women in meals with men, even in Palestine.  Indeed, Gospel tradition indicate that Jesus dined in the presence of men and women.  Both Luke and John, for example, for example, included stories of Jesus dining with Mary and Martha [Luke 10:38-42; John 12:1-8].
