Poor service from management

The N1 City store manager is the rudest I have ever seen at any store. When he saw me in the store he looked at me with disdain and said "what's up" without any formal greeting was not customer friendly, he looked at me as if I had no right to be in the store (not sure if it was racial profiling). I put my items in the isle and left without buying anything as I felt unwelcome. I'm VERY disappointment and do not expect this type of interaction in an environment where customer service is a priority.
