I believe the FCC mandates that cable companies provide cable cards upon request. Used to be the law at least. Sounds like you might have talked to someone who has no clue.
We ran into a situation a few months ago where the cable company provided CableCards, but not in the marina where we were setting up a houseboat. It was due to the switching equipment they had in place for the marina. A stadium may have a similar situation going on especially if they are feeding house programs over the cable signal.
