This IF is based on the "Greensboro sit-ins", where African American students sat at a segregated lunch counter in protest, casting you as one of the students.
This IF seems to be trying to send a message about the merits of peaceful protest, but it's sadly marred by a lack of polish and depth. There are many unimplemented items, occasional mistakes in the text and many places where the NPCs could stand to be fleshed-out a lot more.
There aren't really any puzzles here, so you're likely to see all it has to offer in 10-15 minutes. This doesn't really succeed as an IF, but with some work it could work as the message it sets out to be.
