In the car wash industry, a missed spot on a rim or a perceived scratch is a 1-star review waiting to happen. Most customers won't walk back to the office to complain—they'll just vent on Yelp or Google. By placing a QR code at the vacuum stations or the exit tunnel, you give them an instant outlet.
If a customer scans and says 'My rims are still dirty,' your team can offer a complimentary re-wash on the spot. This immediate fix saves your reputation and builds incredible customer loyalty.
