It's a fantasy role-playing game.

DM: You are Mollymauk Tealeaf, a tiefling blood hunter . You are the member of the famous group of adventurers. Previously, Further along the way, they meet refugees from Nogvurot. After the fourth day of travel, they camp and notice an overturned cart just off the road.
DM: Passes them over. They're all rolled up and ready to go. "As far as repair kits go, these are a little pricier. If you're looking specifically for cart repairs, one kit I can sell to you for, say, 25 gold pieces. That contains all that you'd require for any on-the-road going: wheel repairs, your axle, equipment for keeping your horses attached to your cart."
Player: You wouldn't happen to have any raw canvas I could use to possibly put a bit of a pup tent?
DM: "Raw canvas I can do, but beyond that, the rest of it's up to you."
Player: I'll take the repair kit.
DM: "25 gold for that."
Player: And however much basic supplies to put this together, and I'll figure out how handy I am on the road.
DM: "All right. Rolled canvas here, I've got about 20 square feet of rolled canvas. Will that do?"
Player: Will that do?
DM: Will it do?
