A Stamford convenience store robbed three times is now asking customers to show their faces to the camera before coming in.
Police say the store was most recently robbed last week.
The manager of another store on West Main Street tells News 12 he's been considering doing the same thing.
Several other stores say they wouldn't have customers do that and encourage them to keep their masks on.
They say you can still be robbed by someone not wearing a mask.
