Never really had a problem here before but was at the Auto Zone in Hagerstown Md on October 27th, 2023 between 5-7pm and called to see about a part and the manager On duty answered and seemed kind of impatient and rude. But that's not it, when I was there waiting in a nice size line I noticed 2 young black boys that had already paid for their stuff and as they was walking out the manager yelled at them in front of everyone excuse me did you pay for your stuff. Them showing the receipt saying yes and the man who also works there that rung them up told the manager yes they paid. Even after the worker told him they paid he still made them come back in and show their receipt. Not even 1 minute later a white man walked out and the alarm goes off and he waved his receipt saying I already paid and the manager said I believe you. Seems pretty racist if you ask me!
