As a CS Club member (not an officer) who happened to be studying in there that day, I'd say your group was very loud, but your free money was appreciated.
Obviously if your group didn't pay anything, the officers of the CS Club would be living productive, recreational lives with their friends and family instead of facilitating your liability-inducing nerd gathering. So it wasn't really free money; you paid to get a hoard of strangers onto our campus.
And the library closes early.
