Confused by some lines of a sitcom.
I'm watching an old sitcom called The Golden Girls, and there are some lines which make me feel so confused.
Sophia is working at an restaurant, and she really hates the manager of there, so she calls her colleague and talk about how to protest. At the end, she said:“Good. Oh, and, Edna, bring some sherry. Nobody bought that glaucoma story when you whipped out that reefer last time.
"No. No, you can't put it in brownies.
"I said no reefers. Okay? Good-bye."
I don't understand what they are talking about. What does "glaucoma story" mean? Why is it related to sherry? What does "reefer" mean in here?
I'm not sure if I described it clearly, so I put the video link in here in case anyone can't get my question. The scene I'm asking is in 4:00:https://www.youtube.com/watch?v=pcbJjJQ80fk&t=847s
Another scene I'm confused about is in 13:34. I'm not sure if the action that Dorothy touchs her earring has any specail meaning.
