Kozlowski on Saturday posted a photo of a "Now hiring" sign at a local Lowe's that included the Spanish translation below, "Se aceptan aplicaciones."
Kozlowski tweeted at Lowe's, saying, "What level of customer service can I expect from applicants who need the lower half of this sign?"
Town resident Kathy Jones took issue with the tweet.
"I find your tweet incredibly offensive—especially from someone who represents Mansfield," she tweeted at Kozlowski.
In an interview with the Sun Chronicle, Kozlowski defended his comment.
"My point was that if you're looking to run a business, you should strive to hire employees who can effectively communicate with customers," he said.
