AFAIK it does not exist in Europe, but I meant that these conditions in the EU would not be tolerated. Maybe because of this there isn’t a Walmart in the EU, there are a lot of Malls from other companies and none of these use this practices in their restaurants, mostly with free WiFi for their visitors. Offering free WiFi is already enough of a benefit for them, because it attracts customers, they do not need to intrude on their privacy with an obvious attempt to spam them and make money with their data.
