Maybe its the nature of the businesses I've been in. I can remember two fights in the backroom of a retail business when I was working part time in college. MANY times on board ship in Navy when we were on a long deployment and tempers get short. But the strangest was when I worked a short time in public accounting. Not in the firm itself but out in field at a clients. Twice, once in a construction business office and the other at a not-for-profit who was supposed to be helping at-risk kids and it was between two social workers after hours.
