You can use your credits however you would like. 1 CS credit here, 2 CS credits here, someone may not use their credit one day, you can have an adults-only dinner. It is very flexible, just make sure to keep track to ensure that you don't loose a meal here or there (doesn't happen often, but good to be on top of it).
