A restaurant worker told a man to wear a mask, so the man shot him with a gun, say police

Kelvin Watson (27) has been charged with attempted first-degree murder after police in Colorado say he shot a Waffle House cook who told him he couldn't order food without wearing a mask.

From CBS 4 Denver:

The cook said he told Watson he was not going to serve him and that he needed to leave the restaurant. Watson reportedly became very upset and slapped the cook across the face with an opened left hand, cutting his lip. The cook said he ran to the back of the restaurant and Watson followed him.

Once outside, the cook said Watson made numerous statements to the effect of You better shut the **** up and serve me."

That's when Watson shot him, the cook said.
