James and Florida, who live in Chicago, go to fictional Borgen's Supermarket to confront the store manager about Florida's arrest.
On the bulletin board behind the manager's desk, you can clearly see
a circular for Ralph's Supermarket. These don't exist in Chicago; they are only located in Southern California.
The background in the grocery store is black and white.
Florida is shown putting the roast beef into the oven and only just approximately three minutes later instead of the 20 minute appropriate time of cooking a roast beef, she takes it out and is serving it to everyone. No wonder everyone had 'food poisoning.
