So many businesses that offer free WiFi (secure or insecure) have not updated their routers in ages - I suspect many are still Wireless-G (54 Mbps) at best, or even Wireless-B (11 Mbps).
In one local cafe, the WiFi is so slow that we use our 4G phone to be our wireless hotspot for our Samsung Tab A, and it far out performs the in-house network.
