“It’s not safe here. They have one person on — mostly women — and anybody can come in,” said Joann DeRiggi.

“It’s a shame that people take advantage of businesses like this and try to rob them I guess,” added Angelo Garofalo.

The suspect is described as a white woman with a thin build, last seen wearing a hooded sweatshirt and black sweatpants.
