I have to agree with everyone here,
point #1: There is something bothering him deep inside.
He could've said to you,
"Son, could you please put away the dirty dishes into the dishwasher." Understand where he is coming from, your dad maybe having a stressful week at work, with your mom, with the family, with some bills, with age, with life. Understand that he will find every single little thing about you that can be blown out of proportion.
I remember back in the days,... I had clean the whole house, I had mowned the lawn, I did the laundry and hang it up in the clothes line,... Mind you, I had even cooked dinner for that evening. I swear to you, you wouldn't be able to find a single thing to complain about. I knew my old man was having one of those days. My old man couldn't find anything to point the fingers at me. Out of nowhere he reaps out,
"Why aren't you studying!???".... lol

, that was a classic. 10 years of schooling at the time, he had never once asked me that question. I was thinking... why now?
point #2: It's his kitchen. 
You can do whatever you like with your own kitchen.

What are you doin' messin' up his kitchen

lol
