Was I being a jerk towards this customer?
One time I saw a customer walk in the store without a mask, I informed him of the store's policy that he has to wear a mask while entering the store, he arrogantly told me that he's not a Democrat and that he's medically exempt and walks in the store, when he walked out of the store I apologized to him for making him upset over the mask, he apologized to me in return for being harsh towards me with the way he spoke to me and didn't mean to do so, he also told me facemasks don't work and all what they really do is lower your oxygen breathing level.
I don't get why he would say that he's not a Democrat in a rude, snobby manner.
