I'm inclined to believe him as well, but what did what he was told really mean?
"A few hours later Mr. Berman called and I asked him about the 10 million dollar South American Government ministry order. He told me it was more than that."
Was he saying that the order was larger than $10M? (it's more than that) Was he saying something about a second order? (it's more than that) Was he saying that it wasn't that simple and that it required further explanation? (it's more than that)
Anyone who found the "it's more than that" response a clarification is inferring a meaning to the words that is anything but clear. No one should be surprised that CEO Berman was obtuse...it's not likely to have been unintentional.
