Your uncle’s tea stall.
You. Alone. One morning.

He has gone to the bank and left you the stall. The menu board says chai ₹15, biscuit ₹10, bun-butter ₹25. A regular walks up: “Two chai, one bun-butter,” and slides you a ₹100 note.

No calculator. No uncle. Just you and the queue forming behind him.
