Bad feeling...

There is little worse than talking on the phone to a slow talker, trying to explain a not really complicted retirement thing to them and having that sudden feeling that if you don't go to the bathroom RIGHT NOW there was going to be a lot of problems in the office. Really, what's the professional way to say "Um I'd love to help you but right now I have to GO I'll call you back in 10 no make it 20."
