The Kocian Law Group in Manchester, Connecticut bought an old Kenny Rogers restaurant to use as an office. The building has been renovated to look like any other law office, except for the drive-through window:
"We have drive-thrus for ATMs and we have that customer convenience. Why not a law firm?" attorney Nick Kocian asked.
Kocian wanted to make things convenient for customers to easily drop off and pick up documents. He has been told this is the first drive-thru legal service in Connecticut and possibly the country.
"We represent a lot of injured people," Kocian said. "If you have somebody who's in a wheelchair or somebody who's hurt, it's convenient."
