Dollar Tree

I was completely unaware that there was a law just put into place to wear a mask in our local town. Today dollar tree not let me into store because I did not have a mask. I offered to cover my face With my shirt so I could get something to make a mask and the manager rudely said no, read the sign. It wasn't like I didn't offer to cover my face and I truly anted to get supplies to make a mask as well as what items I went in to purchase. It's one thing to kindly state but another to be rude. I will not shop there again.
