"I was just coming down to the end of an aisle and all of a sudden I heard some commotion and people were getting in the aisle," a witness said. "I looked down there and there was this guy just yelling at someone, and then all of a sudden you see him, you know, take the handles of his cart and just try to ram this woman."
The witness said the man continued screaming at the woman while he pushed his cart into her. She also said she saw another woman try to push the man out of the way.
"I think he was just screaming about the mask," she said. "He didn't want to wear a mask."
Cell phone video taken moments after the incident shows the man sitting on the ground, surrounded by milk that was presumably used to stop stinging in his eyes caused by the pepper spray.
Paramedics took him to a hospital as a precaution.
It wasn't immediately clear if he'll face any criminal charges.
