Pardon me but this is becoming a little tedious. I've just looked up my Concise Oxford Dictionary, and it describes the word banker thus; "Proprietor or partner of public bank, governor, director, etc of joint stock bank".

The bankers are the fat cats, the usurers, the people who make millions out of exploiting markets. The people who work behind the counter in your local branch are not bankers. They are bank employees.
