AITA? My dad has this “sacrifice” system, and i really am not sure if this is right.

Hey all. Recently, i had gone to a family event that I wanted to go to with my mother only, as my father said he was uninterested the previous day. The night before however, he said he wanted to follow along. We said we’d be more than happy for him to tag along. When we reached there, we looked around, and when my mother went to the bathroom, i decided to sit at the staircase and wait for her to come back so we can continue together as look-see as a family, and in the meantime while waiting use my phone. My dad had just returned from helping us parked the car, and he saw me on the phone. First thing he did was to start berating me for using the phone, and said, “I sacrifice my weekend to come out to your event, and you sit here and play your stupid phone? You are wasting my precious weekend by watching your gadget.” Like wtf?! He chose to come along, but then said i’m wasting his weekend by using the phone? Like it wasn’t like i was walking around and stuck to the phone and ignored my parents. I really don’t know, AITA for using my phone while waiting?

He also pulls this “sacrifice precious weekend” thing pretty often, even when l do things that doesn’t appear inherently wrong.

Edit: I definitely am at fault here, because I have overexaggerated the situation here. He was angry, but not to this extent where he swore. I realise I must also understand that I know his work is very stressful as he holds an important role, so the stress is pent up over the weekend. I apologize in advance. I was angry in the moment. He is a very loving father, but he has moments where he is unfair like this.
