Members of the National Restaurant Association in the US are furious with Kevin Federline for appearing in a commercial demeaning fast food workers. Britney Spears' estranged husband recently taped an ad for Nationwide Insurance, which shows him daydreaming about being a rap star, but really working in a fast food restaurant. Representatives from the organisation say the ad, which is set to debut during the US Superbowl broadcast next month (FEB07), is "demeaning and unpleasant" to the nation's restaurant workers. Spokeswoman ANNIKA STENNSSON insists the ad could have been done differently telling, "A sudden change in Federline's career could have been depicted with him holding an unemployment benefit check. It shouldn't be necessary for a company to disrespect others to get its point across. It's a negative, unfair and inaccurate reflection. Nationwide spokesman ERIC HARDGROVE hits back at the claims saying the ad isn't meant "to offend or insult the many fine individuals who work in the restaurant industry." He says it's a "humorous take on one person's life. The focus of the ad is the element of surprise, not the setting of a fast-food restaurant."
