It's a fantasy role-playing game.

DM: You are Percival de Rolo, a human gunslinger . You are the member of the famous group of adventurers. Previously, Percy goes with Keyleth and Tiberius to look for ammunition supplies. Though black powder is not a commonly-sold commodity in Vasselheim, Percy manages to find one eccentric older man who sells it.
DM: "For the barrel? The barrel, that'll run you... (mutters) 4,623 gold pieces for the barrel. However, for the hogshead--" You can see now the spittle dribbling down his chin.
Player: I can! It's as if I can see the spittle myself!
DM: Yes, indeed! "But! For the hogshead, which-- ooh!" And he turns around and shuffles through a bunch of pieces of burlap and sacks and pulls out what looks to be an actual dried and hollowed-out hog's head. "To fill this? To fill this hog's head with it? This'll only cost you 426 gold pieces. Yes?"
Player: How about 400 even, and you can direct me to some ore, as well?
DM: "Ore? I do not work in ore."
Player: I thought you might have a friend.
DM: Make a persuasion roll.
