Anyone who votes Tory (and Reform, although currently at least this is less of an issue in Scotland).
People who go to Costco to buy literally shed loads of bottled water. I’m intrigued every time I go, given Scottish water is pretty nice.
People who have pets, then don’t let them upstairs, don’t let them on the furniture, yadda, yadda - if you don’t like pet hair, have fish or something.
