BROOKLYN - Many Brooklyn business owners say they're worried that the city's upcoming size ban on soda will hurt their sales.

The ban will take effect March 12, preventing restaurants, delis and even movie theaters from selling soda bottles larger than 16 ounces. It will not apply to supermarkets and most convenience stores.

Mayor Michael Bloomberg says the limitation on sugary drinks will help battle the obesity epidemic, but shop owners are angry about what it could do to their bottom line.
