Pick a city, a location and your budget, then run the shop for 7 days. Rent, wages, prep and the weather: try out the real headaches of opening a shop in a little pixel-art store.
Free, no sign-up. The 7 days take about 5 minutes.
More money opens up more locations and leaves you more cushion after opening.
On your own you can serve about 200 drinks a day. With a part-timer, about 400. You'll keep this setup for all 7 days.
You'll keep these prices for 7 days. Above the going rate you get fewer customers; below it you earn less.
Cooked boba has to be used the same day. Whatever's left is thrown out at closing.
Doesn't include your own salary or smaller costs like utilities.
