I'm sitting here at home and the landline rang but stopped before I got to it, so I dialled 1471 to find out who it could be (family members often call it as my mobile reception here is rubbish). It was a local number and seemed slightly familiar to me, so I searched online and discovered it was my GP surgery, so I rang them to find out what they wanted.
The receptionist answered saying how could she help so I explained about the missed call. "Well it wasn't me", she said. Oh right, I thought. Here we go.
She then asked for my name and I said that DH and I both lived here and gave her my name and his. "Well, no-one has called you" she said so I suggested that perhaps the call was for DH. He has a hospital appointment tomorrow for investigation into an ongoing condition, so I wondered if it might be about that, but since he isn't here at the moment I thought I'd better find out in case he needs to contact them. "Well I'm sorry" says she in a very officious voice. "I can't give you any information about anyone else". I pointed out that it was they who had rung first, and I was just trying to be helpful in calling them back in case it was urgent. Not good enough apparently, and she refused point blank to even tell me whether it was him they were trying to contact.
What a pointless waste of my time that was. 
Has anyone else felt themselves rolling their eyes out loud at the brick wall of officialdom today?
