It's a little sad, but I think in this day and age we actually need cafes like this... Luckily my friends are quite good and don't tend to use their phones during meetups and nor do I, but in the past I have had people casually check their entire Facebook feed whilst I'm sitting across from them. I did not appreciate it (and no longer meet up with them, not JUST because of that).

If people want to work, they can go to Starbucks or Costa or any of the millions of places that provide wifi. Not being able to work in this one café that is trying to encourage a different kind of experience shouldn't be an issue.
