I understand your reasoning and try acting decently (even though I probably fail often). Of course it is easier to point out mistakes instead of changing oneself to the better. I think it is commendable that you were so open about your thoughts, which empowered a stranger like me to take a moral shit on your behavior in this specific situation.
I have some acquaintances with weird/antisocial/borderline illegal behavior and never addressed it directly with them, just avoided them.
I've had some acquaintances do some weird, antisocial, definitely illegal things. I can't recall a time when an acquaintance has done something that appears as evil as the situation we're discussing.
Best case interpretation that I can make, ignoring the floor mat. They were micromanaging when their employee wakes up despite their daily responsibilities being temporarily reduced (home owners were away).
If I had a friend doing even the above, I'd at LEAST ask "explain to me how this isn't you being a dick." That's just getting to know them. Don't you want to know the people you're friends with?
