Wi-fi in Santa Monica, Not

I’ve seen businesses, particular food establishments, offer wi-fi as a means of differentiating themselves from their competition or to stay competitive with their competition. However, on a recent visit to Bagel Nosh in Santa Monica, California, I noticed a sign that read “wifi free zone”. Since they did not appear to have any usable signals within their establishment, I assume the notice meant “wifi-free zone” rather than “wifi free-zone”. In other words, they were purporting to offer a place to sit and drink a coffee without being bothered by other customers typing away on their laptops. Well, except those that have high speed broadband service from their cellular provider. And why pick on wifi. Cellphone users can be much more of an annoyance. So is this just a gimmick?
