A coalition of senior and disabled citizens in San Francisco’s Tenderloin district launched a campaign against the sale of cheap, high-alcohol-content wines in an attempt to reduce the number of drunks on the streets. Betty Mangual said at a news conference that she and others are afraid to go out and are “prisoners in our own rooms.” Phillip Faight, a member of “A Tenderloin Committee . . . Safe and Sober Streets” and the owner of two bars in the area, said he does not carry the cheap wines. He offered liquor store owners chances to win $100 bonds if they will not sell the wines.
