KNOXVILLE, Tenn. (WVLT) -- Eloise Rodgers lives alone and has for nearly 30-years.

"If I was going to let someone in I would ask for their I.D."

But how does Eloise know that I.D. is real? K-U-B is one utility that spends a fair amount of time working in neighborhoods. For her, there's more than an I.D. that gives her peace of mind.

"I would look at their truck first. They always have it labeled. Then I would ask for the I.D. before I let them inside," said Rodgers.

"K-U-B encourages customers to always ask for a photo identification badge when anyone claiming to work for the utility comes to their home," Grace Whiteside from KUB told WVLT.

Inside Kay Uniform, you'll find literally hundreds of items for law enforcement.

"We first want to see credentials, I.D. and department I.D," GM Matt Long, said.

But that's just for specific police and sheriff's department gear. If it's generic, Like this cap that simply says "police," anyone can purchase it. But in the past, there have been those posing as law enforcement trying to buy official uniforms.

"Twice that I know of in the three-years I've been here."

Something Kay's takes seriously.

"We contact our local Sheriff's Department, which has a pretty quick response time to our parking lot cause they know where we are."

In 27-years, Eloise hasn't had a problem, but promises to be more cautious. And keep to her time-tested security system.

"I have a huge dog. That's just my way of dealing with it."
