Visible crew/equipment: When Lucy and Ethel are at Caroline Appleby's apartment, a few actors' tape marks are visible on the carpet near the couch and side table, where characters will stand at different times during the scene. (00:06:00)
Continuity mistake: In season 2's episode "The Ricardos Change Apartments" their new apartment number is "3B", but in this episode when Lucy's at her audition she tells the casting agent that her apartment number is "3D" (deliberately done in order for the 3D joke to work), and it's in the next episode "The French Revue" that we see the new number "3D" on the door.

Answer: There is no reason. It's a just a silly plot device, typical of the era. Women characters were often portrayed as making uninformed assumptions or decisions.
