I walked in and a girl asked if I had a mask. I told her yes I do. She then yelled across the store telling me to put it on. I told her I could not. As I was trying to tell her there was a medical reason why she told me I had to put it on or the cashier would not allow me to pay. I continued to shop and she walked right behind me talking on her phone saying "No you don't need to come up here. It's just some man causing problems. No don't come up here, you will blow him up". I took this as a threat. I do not appreciate your employee threatening me. I assure you if anyone had come and tried to "blow me up" I would do anything I had to do to protect myself. I would like to be contacted. I did speak to the store manager. At least I was told she was the manager. She was also in the store with no mask but did pull her shirt over her mouth. User's recommendation: Don't be so rude.
