does anyone's parents have double standards? not sure if this is normal

[background first off, I am 30 years old and staying at my parents for a couple of weeks until I move out at the end of the month because of a serious physical illness. I had to terminate my rent at my old place and stay with my parents until I can sign a lease for a place closer to work]. my parents expect me to wash my dishes right away right after I eat. I always wash my dishes right away to the point where my parents don't even realized I cooked a whole meal because all the dishes are put away. one instance, I left one bowl to soak because I put oats in the fridge and some of it was stuck on the bowl. after I put it in the sink, I sat down. immediately after I sat down , my dad came to down to the sink and made a whole bunch of comments saying that I left my dish in the sink and should wash my dish right away. I explained that the oats are stuck and it needs to be soaked before I wash it and I literally just put it in the sink before he came down. he still insisted that is should be washed NOW and that he always washes his dishes right away (when this is not true. when he is working, he always leaves a pile of dishes in the sink). so this got me upset and I told him I can't do them right now because I am letting them soak. he starts raising his voice and telling me why I should do it now and that I am not acting like an adult. then later, he holds a grudge with me and tells me he can't come with me to check out a new living situation the next day because he is going to eat breakfast with my brother instead. anyone else experience this with their parents? not sure if this is normal but am happy to move away soon
