OP,
We "broke" some of the rules as well! My BIL ordered his daughter an adult breakfast. We shared at Sci-Fi. I loved, loved, loved Sci-Fi! The only place we were told we couldn't do something was the CS place in Mexico.
We got those jumbo chocolate milks as either a drink or dessert credit. We substituted bottled water for desserts. And that $14 rib/chicken combo at Cosmic Ray's is definitely the best use of a CS credit!
