Some retailers go worse, they had someone screenshot the QR code, then printed out a bunch of them at half-size so they could plaster them all over the place (at every table). But because they resized them using some dithering pattern, they start out slightly blurred. It gets worse when they're exposed to moisture (they're sticky-taped to the tables/counters) as the ink then bleeds. Scanning this is a pain.
