A couch surfing hippy my room mate let stay with us for two horrible weeks decided to make some oily vegan garbage in our stock pot for a “thank you dinner”. I took one bite and almost puked from all the veggie oil she used. I asked if I could skim it off the top of the pot and she got all pissed, grabbed the pot and tried to flush it down our (only) toilet. It immediately overflowed a bunch of oily, undercooked, and flavorless crap onto our bathroom floor. There was much more drama after that involving an expensive bike, an ex boyfriend, unpaid roto-rooter bill, a rental steam cleaner, and new rules involving house guests. bonus: she used all of our food to make it, she bought nothing herself!
