i think it is rude of him not to appreciate your effort in making a meal for the family.
it takes some timing to prepare all the meal so that it can be served all at once. it is not something that can be delayed for 15 minutes because then it would be overcooked or cold.
drinkers do not like to eat and then drink. they get more buzz drinking on an empty stomach, so that the alcohol goes straight into the bloodstream.
this kind of "i'm the king of the house and everyone will eat when i sit down to eat" is chauvanistic, controlling, disrespectful and yes, rude.
