I'm looking for a word to describe one's behaviour that is unnecessarily complicated.
For instance, let's say John, he goes to use the public toilet. Unlike most ordinary people who just uses the toilet, flush, and then leave, he's behaviour is unnecessarily complicated. Every time he goes to the toilet, he would first, remove his outerwear, this includes his jacket, pants, and even his socks and shoes. He would then, wipe the seat with toilet paper and then layer the seat with the toilet paper, and puts all his attire back on afterwards.
What's the word to describe this kind of behaviour?
