Marshalls

I went to marshalls on march 31, 2019 around 5:45 p.M. And i'm aware that they are closing in 15 minutes, as I walked out to exit near the tills, I just happenend to make a quick check on prices of some items, an employee approached me and informed me that the store is close and if i'm buying it's ok and if not I should exit, the problem is the way she told me is a way I felt that is not very professional and have a tone of racial profiling.
