Rant - Shops that block your mobile phone signal

I am getting very fed up with shops that are using blocking equipment to stop your mobile phone working within their stores. Sainsbugs and Tesco's do it and this now means that if I am on a 'job' one of us has to stay outside the store with 2 mobiles in case we get an urgent call.

I also believe that some cinema's are doing the same thing (which I can understand) but for Pete's sake, please put a sign up to say that you operate this kind of thing so that we can decide whether we want to shop in your place or not.

One day someone is going to miss a life & death call because they don't want us rushed in their store.....:x :x
