Tour Guide: "Welcome to Base Camp! We're halfway to the top... ...and it's getting a little darker. Take a break, warm up... ...and tell others about your adventures so far!"
You: "I think I am only going up one more floor. Bye."
Tour Guide: "20 coins."
Tour Guide: "I gave you a tour, you owe me 20 coins."
You grumble and reluctantly give the tour guide 20 coins
