I work at a financial institution. When the screaming started it did not go over well - fortunately there were no customers within earshot at the time. It was the first phone that almost turned into a career limiting device.
I have actually heard of this happening to a couple different people now with Wavesecure, which has made me sorta reluctant to continue using it. I can just imagine how well that would go over with my commanding officer if this happened in the middle of a formation or something...
