Just got pepper sprayed for not wearing a mask

Just got a call from my buddy in Michigan. He went into a gas station without a mask (says he does it all the time). When he came outside a guy in a car said to put his mask on, he replied with eat a di*k. Guy got out of his car and pepper sprayed him. Buddy jumped on the guy took his pepper spray and sprayed him back. Cops got called and the guy who sprayed him is now under arrest for assault with a weapon. Crazy that people even care this much about someone not wearing a mask outside.
