Video from inside the smoke shop shows 37-year-old Joan Nunez and Pedroza apparently arguing.

A store employee told CBS2 the argument started when Nunez held the front door open for Pedroza, then criticized him for failing to say "thank you."

The argument escalated into a physical fight, which spilled onto the sidewalk outside the shop.

Police say Pedroza then pulled out a knife and stabbed Nunez before taking off on an e-bike.

Nunez was taken to a local hospital, where he was pronounced dead.
