I think this sort of thing causes confusion.
One I was sent to a CIB meeting at a hotel and expected to be in a Chartered Institute of Bankers meeting.
I followed signs which said CIB and sat in the room. I was a little surprised I did not know anybody there.
After about 30 minutes I realised I was in the wrong meeting. I was in a Chartered Institute of Builders meeting.
The meeting started with a talk on finance so it took me 30 minutes to pick this up.
