By David Adams MIAMI (Reuters) – Arby’s sandwich chain fired a South Florida restaurant manager and suspended a clerk after an unfortunate police joke led to a complaint against staff at a drive-thru. Pembroke Pines police officer Jennifer Martin, accused the clerk of refusing to accept her credit card when she ordered a meal on Tuesday at the restaurant a few miles northwest of Miami. “He doesn’t want to serve you because you are a police officer.” Martin was eventually served, but decided to return her food and was given a refund.
