This woman drives me nuts. Such a stupid tantrum.  You know, she has a choice.  If she don't like the mask policy at the store, then DONT GO IN THE STORE! Order online!  Do not give me a tale on how you can't wear it, blah, blah, blah.  It isn't about her.  She knew the policy before entering the store. Or find a store that doesnt give you a hard time if you don't want a mask on.
But it isn't a big deal.  For a 10 minute ordeal in that store, suck it up.  But throwing a tantrum, knowing you will be on YouTube, is just pathetic.  
Whether or not the mask works for you is irrelevant, but stop violating the store policy.
