It is customary to serve parents (as they are also older) first at the table. However, my father and mother a”h always complained and told me to serve my husband first, while my husband insisted that I serve them first.
We must have similar families.
Whenever we have my mother over for Shabbos and I make HaMotzi, my wife would always insist that I give to my mother first while my mother would insist that I give Eeees first. Both viewed the other as being more important in this respect.
