Apparently some cafe owners, in places like Seattle, are pulling the free wi-fi out of their cafes, at least some times of the week. Why? Because the wi-fi users are staying too long and buying only one drink or none at all, taking up tables meant for four people, and not talking at all (a problem in cafes that owners mean to be social hubs). Many are belligerent when asked to leave or order another drink. After all, it’s a right to have wi-fi, isn’t it?
