its quite hard to tell u over the net bout this. I can point him
out to you giving a "Yes,he's attached answer" or vice versa. It
also varies on the situation. I dont think its something can be
teached, rather a skill that is acquired and honed.
One of my friend was at a cafe with a friend. They ordered soup of
the day. The waiter told her they ran out..but she immediately cut
him off and say "Dont lie, just bring us the soup". Sure enough
they were served soup of the day few minutes later. Now how can she
tell that this waiter, acting professiionally with no tell tale
signs he was lying? From his voice..
