Customers can't walk into the Q and A convenience store in Farm Pond without seeing the signs.
"And I have a sign that I'm going to put here and we're going to get more signs printed out this week," said owner Allen Tawati.
Tawati showed Channel 9 the changes he's made and the ones he's going to make at his store since police approached him several months ago with their concerns about groups of people -- many of them teenagers -- hanging out and causing trouble.
Customers had noticed them, too.
"There's a lot of people hanging around -- no reason," said customer Aljay Davis.
Davis had noticed those people aren't hanging around anymore and Tawati said that's because police are backing him up.
"We now call police and we let them know what happened and we let people know we're not going to take it," Tawati said.
Perception is one thing, but police said the changes here are real. Police said crime in the area is down by 37 percent.
"The people who live there, they're like, 'We can really tell the difference. It's a lot more quiet out there," said Lt. John Thomas with Charlotte-Mecklenburg Police Department.
Thomas said Tawati has been working with them for several months now and the problems aren't all gone.
When Eyewitness News was at the store Wednesday afternoon, three young men said they weren't happy about it.
Tawati isn't backing down now.
"The police assure me that, 'We are going to be behind you, so don't worry.' A little networking is going to be good for everybody," Tawati said.
