Czech restaurants often advertise as “Wi-Fi free” and not only do they take no measures to block 2.4, 5 and 6 GHz signals from outside, they have a Wi-Fi network of their own!
(It’s a common language error, they translate Wi-Fi zdarma (“Wi-Fi for free”) literally, not caring about different preposition/word order rules in English)
