I was a master at getting free food in college. I'd just walk into events, sometimes ones I wasn't invited to, grab food, and leave. Oftentimes my college wouldn't post bouncers at every entrance to the buildings, so getting into private stuff was ridiculously easy.

There was also a time where going to the career fair would get me extra credit for a class. You had to pay to get in, though. I just walked in the side door, got the proof that I was there, took some food they were serving, and left.

You can do so much if you act like you belong.

10/10 would recommend doing this as much as possible.
