Dollar Tree

I was looking at nail polish and had 4 polishes in my buggy to purchase which i opened to see the colors when the manager Angela yelled from across the store register area..."You can't try on nail polishes!" In a loud and rude manner to me!I told her that I was purchasing the nail polish.I have never had an associate yell from across a store to me ever in my life!It was completely uncalled for and very bad customer service not to mention embarrassing as other customers in the store heard it.I purchased over $15 dollars during my visit today including 4 nail polishes and shop this store often but will never return after this incident today.The manager Angela needs proper training on customer service and as an adult I would never speak to another adult in that manner.I am an educator and get many of my school supplies from this store for my students but will not be visiting this location again because of how I was treated today.
