This is pretty low-key, because I don't know that many people who have funds to throw away, but my current roommate.
She eats off paper even though she has perfectly good dishes. She makes lots of fancy foods, only to leave it sitting out until it spoils and then throws it away. She goes through paper towels like toilet paper and uses them for everything. She generates SO MUCH TRASH. I can't help but think how much money is being wasted on all this stuff.
