This is fine.
This is fine, if it's actually in the morning, but it takes a little longer.
This is fine for someone who is a receptionist or otherwise directing calls. A better variant for other folks is "Jones and Co., John Smith speaking."
Managers that make people do this sort of thing should be shot. When I was a kid, we had a man from the telephone company come to speak with us at school, probably around third grade. He explained that the key to using the phone was to keep your call short and get your business done while being polite about it. Anything that extends the call needlessly is a bad idea, especially if it's possibly offensive and condescending to the customer like this is.
Yes, it's very popular, because it's easy for managers to do this and get a notion that they're making their employees care about customer service. In fact, this sort of thing makes employees LESS apt to care about really taking care of customers.
