It's a fantasy role-playing game.

DM: You are Scanlan Shorthalt, a gnome bard . You are the member of the famous group of adventurers. Previously, On Vax's request, Gilmore procures a favor for him with the Lyceum. Vax also purchases three enchanted daggers, presumably as a gift for Kynan Leore.
DM: She looks at you, and goes, "You have been good patrons, and you have been much kinder to me than others. We'll put this one on the house. We'll call this on the house." And as she takes the vial, sets it down, and she pulls out another book that she shuffles through, puts it up, turns through a few pages, until, looking through, "This here would be a Potion of Fire Breath. When imbibed, it should give you a temporary time period of the ability to breathe fire, much like a relatively young dragon. This one in particular is fire. There are many different vials like this that pertain to different colorations of dragon, but this one is specifically for the red."
Player: Thank you so much. Thank you. Well, thank you so much. Two more questions, then I'll leave you alone. One: where can I go get business cards printed up, in this town? It's a calling card? Never mind! Forget it.
DM: "Like a flyer?"
Player: Yes!
DM: "Those can be printed. There is a-- actually, a pretty well-designed print facility not that far up the road."
Player: Oh, great! Thank you; I'll go investigate that. And one other thing: you know those books that my friend was asking about? Could we maybe make those happen for her? I know that you had quoted her a low, low price of 25. I'd be prepared to pay even more than that for them. And compose you a little song about yourself.
DM: At which point, for the first time since the entire time you've been in the shop of Gilmore's Glorious Goods, you see a slight grin creep across her lips. She goes, "How could a lady say no to a song? 25 gold! The price stands."
Player: So I have to pay you and sing to you?
DM: "We run a business, here, yes."
Player: All right.
DM: She pulls the books out.
Player: I bring out my-- something. (sings) Sherri baby, Sherri baby, Sherri, won't you come home tonight? Come home tonight? You better ask your mama. Tell her you're without a gnome! Why don't you come home to my keep!
DM: "Pay for the books!"
Player: Okay, here you go!
DM: You can see, her face is flushed and she, (clears throat).
