The characters make many references to visiting Jack In the Box, an American fast food chain. Whilst a handful of Jack In The Box outlets were in Florida in the 1970s, they were all closed down by 1980 and didn't return until the 2020s. Jack In The Box is very popular in California, where the show is filmed, and writers made the decision to ignore the anachronism in favor of fulfilling a paid product placement.
Many misplacings of '90s cultural items throughout the series are intentionally done by the show's creator, Nahnatchka Khan. (i.e. modern day clothing in the '90s.)
