Where they are in control....
I will admit it, I am old (ish) and the amount of calls I take from callers who can't structure a phone call and achieve an outcome is boggling.
It is not every young person and there is certain young man who works in Manchester who calls our company and is unlikely to ever read MN, but if you are David from New Horizons you are brilliant. 
But back to my point, the amount of young,youngish people I take calls from who can't do it is .................
I took one the other day, and the caller who didn't sound like a school leaver, but younger than thirty (imo) , I opened the call, with name of company, good morning.
She replied with.................... silence .......oh yeah can I speak to , continued to get the whole call wrong.
I floated the idea at the weekend amongst friends of setting a company offering telephone training, guidance in setting out a basic letter etc.,,,
They were all in the 40/50 bracket and reckoned there was a gap in the market.
I take early retirement in a year or two and would happily look into doing it, if I thought there was a market.
Opinions please.
