I used to drive a minibus and on one journey taking people home one lady on the bus looked very unwell. I phoned the emergency services and said I was on the A321 between Twyford, Berkshire
and Wokingham just south of a road called Broad Hinton. I thought this was fairly clear.
But then the operator asked where Twyford was and where Wokingham was. So I ended up having to say that Twyford was about halfway between Reading and Maidenhead and then the same thing for Wokingham. And all the time my passenger was looking more and more distressed.
Can't say I was very impressed at all with the call handling aspect. Once the ambulance services arrived they were of course excellent.
