Google review QR code for food trucks

Stick it at the serving window, at eye level

People look at the window while they wait for their name to be called. Put the card beside the pickup shelf or on the menu board, where it is read from a step back. Laminate it or slide it into a clear sleeve, because a truck's card meets rain, steam and greasy hands.

Send the code away with the food

Food from a truck is usually eaten somewhere else: a bench, a car, a desk. Print the QR code alone as a small sticker for boxes, wrap paper or napkin packs, so the request arrives when the food is being eaten, not while the queue is long.

Don't ask at the window while they wait

Google's policy says businesses should not pressure customers to leave a review on the spot. Let the card do the asking, and never make the review part of getting the order.
