1. Customer requests a token for today (or taps a WhatsApp/website link on arrival).
2. They are given the next available token number in the queue for that day.
3. The "Currently Serving" number updates live so customers know their wait.
4. Admin marks each token as served once that car's wash is complete.
5. Optional: set a daily token limit (e.g. max 40 cars/day) so the queue doesn't overrun closing time.
