Faraday Cage?

Nope, not possible.

However, the phone signal drops dramatically when you're inside this recently opened cafe in the village. There's a suspended metal grid for the lighting, which got me thinking?

Tinfoil hat time! 

This building used to be a lawnmower sales and repair place. I bought my lawnmower here. Now it sells skinny latte and it's busier than when it was a lawnmower place. Though, sadly, you can't Insta your avocado on sourdough if you're not on the wifi, no phone signal....

Ps first time I've been, don't think I'll be rushing back. I prefer the other cafe with the wipe down cloths and sausage and egg butties.
