Goal: make boba tea from scratch — milk the cow, boil tapioca pearls, heat brown sugar syrup, brew tea, and assemble drinks.
You have 5 minutes to serve as many customers as possible. Pearls take 20s, syrup 15s, tea 10s. Prep in advance!
After serving, run the register — accept cash (with change), card, or QR payment.
