NEW YORK (CBSNewYork) — The manager of a Manhattan coffee shop says he is concerned for the safety of his employees because of violent incidents at the hands of the homeless.

Manager Matt Fury said since his “Think Coffee” shop opened at 14th Street and Eighth Avenue in Chelsea, he has had to constantly referee what he calls violent homeless crowds repeatedly causing disturbances and even throwing chairs around.

“We’re very concerned for our employees who have to be here for pay and also for the neighborhood,” Fury told 1010 WINS’ Glenn Schuck on Thursday night.
