I just phoned the Assembly operator to ask to be transferred to an AM's office. She told me I needed "Colwyn Bay".
"But AMs' offices are in Cardiff Bay," I said.
"Yes, but the switchboard is in Colwyn Bay."
Having been transferred to Colwyn Bay, a lady with a north Walian accent said: "This is the information line and booking line."
It's all a bit frightening.
PS. The person I actually wanted wasn't in.
