Gas station owners say the city's latest move to curb drunken driving is about as appealing as warm beer.

Uncooled beer and wine are the only alcoholic beverages gas stations can sell now, thanks to a recent ruling by the city's planning commission aimed at making chilled spirits less convenient to drivers making pit stops."It's going to hurt business," said Mehrzad Hamzeh, owner of a Shell station located next to a grocery store that can sell cold beer. "People don't want to take warm beer home and then wait for it to get cold in the freezer. This is a ridiculous law."

City officials defended the rule, arguing that the rising incidence of drunken driving requires drastic countermeasures.

"The city is trying to send an appropriate message - alcohol and gasoline don't mix," Planning Commissioner Mike Gorman said.

Walnut Creek is a San Francisco Bay area city about 10 miles east of Oakland.
