If you're vaccinated or not, are you okay or against wearing a mask?

So at my job, my boss told me to shadow the managers since I applied for full time and the management program. Today I witnessed a debate between the manager and customer. It was about the mask. Where I live, for some stores or restaurants it's mandatory to wear a mask even if vaccinated, and if the city finds out that the rules hasn't been followed they can and will shut down the restaurant/store/gas station, etc... So my manager came to me so she can teach me how to approach a customer and kindly ask to wear a mask, tell them why and apologize and to also let them know if they don't have one we can offer them a mask for free. So when we approached her, she started yelling how she doesn't want to wear a mask, and how she doesn't believe in masks, or covid, and ranting how she had to get vaccinated even though she didn't want to, blah blah blah. So my manager apologized and told her she had to leave the store, she didn't leave and instead, she called the police on us, police came, asked her questions and they came to us, we told them our side of the story and the cops were on our side, and at the end she left, I honestly don't know what she was expecting to happen when the cops arrive.
