Before I ran to investment banking and legal, I had the misfortune to temp a lot at commercial banks like Chemical and Manufacturers. The most psychotic and unprofessional people I have ever met have been the ones at commercial banks (the only possible worst working environment would be insurance companies).

I once walked into one commerical office and this bitch was screaming. This bitch was screaming at the top of her *ucking lungs and everyone was acting as if this was normal.
