I chug a whole water pitcher at my school's cafeteria if someone asks to borrow it

Each time I go to my school's cafeteria, I bring a water pitcher filled halfway or more to hydrate myself. I usually don't plan on finishing it, but most of the time, a group of students will ask me to borrow or use it just because I'm alone and "He's not gonna drink an entire water pitcher dude!", so to assert dominance I just chug it really fast in front of them and leave fulfilled.
