Debt collector goes too far

A Des Moines debt collector got fired for insulting and belittling people while demanding payments for their creditors.
After receiving complaints, his company's officials queued up tapes from 29-year-old Justin Saiz's calls. Here's one, as described in the Des Moines Register:
"At one point, Saiz began mocking the man, saying, 'You sound like Goofy: yucka, yucka, yucka.' Saiz then told the man to 'stop flapping your gums.'"
Saiz said his conduct was tolerated and even encouraged by managers who wanted him to "stir things up."
