A student is talking with merchant she is already familiar with.

Studious Student: “Good to see you again, sir. Do you come here every day?”
Shrewd Royan Merchant: “Of course. Laziness never pays!”
Studious Student: “But why come to the camps instead of the Royan Market at the Academy?”
Shrewd Royan Merchant: “Before I answer that, tell me, besides the cost of goods, what else eats a merchant’s profit?”
Studious Student: “Rent? Wages? Storage? And…”
Shrewd Royan Merchant: “And transport.”
Studious Student: “Oh, I get it now! Because this camp is near Bjartr Woods, it means a shorter trip and lower transport costs!”
Shrewd Royan Merchant: “Hahaha! The mind of a merchant, you have!”
