At the
Safeway on San Francisco’s King Street, you now can’t leave the store unless you buy something. The
Mission Bay grocery store recently installed new
anti-theft measures at the entrance and exit.
New gates at the entrance automatically swing open when customers walk in, but they’re set to trigger an alarm if someone attempts to back out. And if you walk into Safeway and change your mind about grocery shopping, you might find yourself trapped: Another gate that only opens if you scan your receipt blocks the store’s sole exit.
