You were dressed as a priest and were driving around in a handicap cart at Costco. When asked about putting the mask on properly to cover your nose, as required by Costco, you whined about not being able to breath, probably like you were not able to walk as you hopped in and out of the powered handicap cart and surprise, walked around.
If you are too sick to wear the mask properly, you are too sick to go to Costco. And too stupid to realize that you are probably infected by the Coronavirus by coming in contact with dozens of ill parishioners on a daily basis. The mask prevents transmission more than it protects the rest of us, who are also having problem breathing with masks.
Someone was shopping with you so you didn't absolutely have to be there, but because you were a poor handicapped priest no one seemed to notice your assholery. I hope your god strikes you down.
