Three's a Crowd (S04E13)

Marvin, the proprietor of Falls Taproom in Philadelphia, reaches out to Charles Stiles after hearing unsettling whispers about a rift between his girlfriend, who also manages the bar, and his best friend. The Mystery Diners reveal deeper issues tied to Marvin's friend, a regular patron, who has been showing up drunk and bothering both customers and the manager. After a confrontation, Marvin decides to sever ties with his friend and bars him from the establishment. In a later discussion, the ex-friend expresses regret for his actions and vows to make amends. Marvin then offers an apology to his girlfriend, who agrees to forgive him only if they go shopping the following day.
