Bar- and bat-mitzvahs may bring lots of people to shul but visitors still appear to struggle with Shabbat etiquette.

Security staff at one United Synagogue confiscated a staggering 45 mobile phones and two cameras at the door on a recent Saturday morning.

In another instance, the warden of a synagogue was asked by a visitor if his shul had Wi-Fi. But the biscuit must be taken by the man who managed to smuggle his mobile in to the service and was caught texting for a takeaway.
