BOSTON (CBS) – Norfolk District Attorney Michael Morrissey is pushing a strong message this weekend to bartenders: Watch what you’re pouring into that glass, and more importantly, watch who you’re handing it to.

He’s distributed signs that are now up at 800 bars and restaurants participating in a campaign to remind bartenders not to over-serve.

“We really want to reach out to the people that are on the front lines,” says Morrissey. “The bartenders, the waiters, the waitresses…their actions can go a long way to serving a life.”

It’s a message that hits home after a fatal accident in the same county early Friday morning.

The District Attorney says the woman behind the wheel was celebrating at her boyfriend’s 50th birthday party before she crashed in Wrentham. He died in the seat next to her. Prosecutors are now considering drunk driving charges.

The signs that tell servers to “observe, don’t overserve,” were paid for with money investigators confiscated from convicted drug dealers.
