Watched a lady walk around the store with her mask down around her neck. Employees ignored her and didn't say anything. So I did. I said Ma'am can you please put your mask on? She went to put it on and then she decided her name was Karen and decided to scream that it wasn't any of my business and she has asthma. Plenty of people came over to the screaming but no one backed me up. I asked her one more time and then walked away while she continued to rant. I'm so disappointed in people right now.
