I catch Milton in an unguarded moment (he'd just had one of those conversation with T.Aldous where you wonder which of you stepped out of an aeroplane without a parachute).
"Why didn't they put a 'phone line in at Catty the same time as they put in the fax?"
"Because T.Aldous has decided that it's going onto the council switchboard."
"I thought we were putting it onto the switchboard at the end of next year as part of the council's VoIP roll-out."
"A couple of weeks ago T.Aldous was talking to somebody in the Town Hall lift who said that it should be possible to put a VoIP line into Catty to put it onto the switchboard. So that's what we're doing."
"So that it won't cost anything for T.Aldous and Julia to ring Catty Library."
"Have we sorted out the publicity for the new 'phone number?"
"I'll need to know the number so's I can make the changes in the web site."
"Good luck to you."
"We don't know the number?"
"Not yet we don't."
"So what's the plan?"
"I've told them that if they're going to change the arrangements at this late stage of the game they can sort out the consequences themselves."
Sounds like our way of doing things... If you don't like the answer you get, keep asking people until somebody gives you the answer you want, however much it screws up your project.
