"Roz is like one of the guys. She knows more dirty jokes than Duke."
Martin (John Mahoney)
Frasier (Kelsey Grammer) was well acquainted with the need for a watering hole where one could go — and everyone would know your name and they were always glad you came. He had spent several years frequenting Cheers! before leaving Boston to return to his hometown of Seattle.
His father's physical therapist, Daphne (Jane Leeves), had come to the U.S. from England and had been feeling homesick when she discovered such a watering hole, called the Fox and Whistle, that catered to Britons in the Seattle area.
So, naturally, when Frasier's social life was, as the saying goes, in the pits, Daphne decided to share her secret getaway with him. Frasier tried to join his father (John Mahoney) and Roz (Peri Gilpin) in playing cards, but it quickly became apparent that wasn't the answer, and Daphne took pity on him. She told him she was meeting a lonely friend of hers, and they might hit it off. Frasier, after reminding Daphne of his policy against blind dates, nevertheless agreed to go when he learned that Daphne's friend was an underwear model.
Daphne's friend, as it turned out, had just become engaged; Daphne thought that would be it for Frasier, but she didn't count on him taking such a shine to the place. When she emerged from the ladies' room with her friend, she found Frasier singing a spirited version of "Beer Barrel Polka" with the rest of the bar's patrons.
Before long Frasier was going to the pub every night, and Daphne was feeling like her space had been invaded. The bar, after all, was where she went to get away from her work and home life.
And when she presented it that way to Frasier, he understood. He recalled the bar in Boston and the void it had filled in his life, and he graciously offered to bow out, conceding that Daphne had a history there whereas he had only been coming there for a couple of weeks.
Frasier (Kelsey Grammer): You've got to be careful what you bring down to the pub with you.
Daphne (Jane Leeves): Tell me about it.
Then it turned out that Daphne really didn't have such an extensive history at the pub after all. She had only been coming there for a few weeks more (or a fortnight, one of the English words Frasier was all too eager to embrace) launching a battle over the bar.
They decided to settle it with a game of darts, which Daphne lost. In the process, though, Frasier made some uncomplimentary remarks about Britons and the Motherland and was run out of the bar by the patrons.
So Frasier skulked back to the cafe, where he found Niles (David Hyde Pierce) drinking a cup of coffee. Earlier Frasier had slighted Niles, and Niles could hardly wait to gloat by asking if "it's over over there."
He already knew the answer.
I always thought one of the nice touches of this episode was how it opened and ended with vignettes featuring prep–school versions of Frasier and Niles bickering as brothers do but in their peculiarly elitist and snobby way — demonstrating that some things (and people) don't change.
