A black man in a blue suit is talking on a cellphone while smoking.
The man is talking to his friend on the phone
There is no reason why a man can't talk on his phone to someone other than his friend.
The man might be talking to someone who is not his friend, but a co-worker or employee.
A man can talk to someone who is a friend or is not his friend or someone who is becoming his friend or who is no longer his friend so there is more than the possibility that man is talking to his friend; a man cannot talk on a cell phone and to a friend who is talking on the phone at the same time.
