A survey of what bugged Brits most came out with 'problems' like not having a Wi-Fi signal, satsumas with pips and the 5p bag charge. Having to use opener because the tin doesn't have a ring pull also made the cut.

This just narrowly pips at the post finding your satsuma has pips in it or receiving a 'we missed you' card for a failed parcel delivery (this infuriates me most, especially because the postman can't be bothered ever to ring my bell to see if I'm in).
This article lists the 50 things that bug Brits the most. Are there any here you get steamed up over? What bugs you more than anything?
