"It's been several weeks now that [there's] zero carts. That's a problem."

Hoping to stop theft, one San Francisco Safeway is no longer allowing shoppers to take their carts outside the store.

An employee at a Market Street Safeway told NBC Bay Area that dozens of shopping carts have been stolen recently. Published reports say as many as 160 have been taken in the past few weeks.

Now, shoppers can only use the carts inside. Large poles attached to the carts are designed to prevent anyone from trying to take the carts through the front doors...

"I love my neighborhood, but the stuff that I've seen happening in these parklets, like the fights, the drug use, the harassment, it's not good," Jhia Jackson of San Francisco said.
