We started a petition and asked for signatures at the on-campus cafe.
After a few days, the administrators asked us into their office for a chat. They asked us stupid questions and tried to talk us out of our petition. When it didn't work, they eventually caved and didn't do the carpet that year.
They waited for the next year. Then a couple years later, they put back the tile.
I don't know why they were so scared of our petition, but I'm sure this is another situation that could benefit from one. It sends a very clear message about the situation to people very high up in the food chain. And I'm sure it could get a ton of signatures.
