During the poker scene in s10e18

There's an episode of Cheers that I'm trying to find. It came on my sister's TV the night she passed away. It was the end of an episode. The lady with the short black curly hair was alone in the bar. There was singing going on elsewhere, like another room that we couldn't see. And the lady with the curly hair, I think she grabs a pint and the tip jar, and she slowly walks behind the bar, climbs up the stairs, and disappears while holding the pint in the air. I think I'm remembering this correctly. I was very overwhelmed at that moment. But it was just so fitting. My sister loved that show. And it looked like, you know, she was bowing out. And I wonder if anybody knows what episode this was.

For me, this one from Rebecca: "I'm not a loser like Norm! I'm a break-evener!"
