Overview: Charles helps the owners of Redballs Rock & Roll Pizza in Moorpark, California after finding discrepancies in their pizza supplies. The Mystery Diners point to bigger problems with their manager and one of the waitresses behind the discrepancies: the manager has instructed the waitress to ring up a slice of cheese pizza as beer to pay the bands with beer, in addition to using his own bouncer at a door to collect money from patrons at the door and inside the restaurant for himself, and withholding money payment to the bands. With one of the bands about to take their truck in response to being owed money, the male owner run out and stops them from driving off. He and his wife both confront the manager and waitress involved and fire them both.
