When the owner has turned curbside on, a pickup guest can say what they are driving at checkout. The card reads:
🚗 Curbside · silver Civic, ABCD 123
Bag it, tap ✓ Ready as usual, and walk it out. The guest's text says the order is ready; the car line is for you. A card without the line is a walk-in to the counter.
