A manager from the othyer Glen Burnie store called me this morning. She told me she was not sure why I was told the registry in her store wasn't working because it seemed to be working to her. She admitted sometimes new employees will say that of they are unsure of how to work it ... In any case, she assured me that it was in working order and that I should inform her or another manager immediately if I was told differently (admittedly I should have done that in the first place).
She also said that she was going to call neighboring stores to see what was wrong with their machines because she was upset I had gone through that.
Way to go, Walmart for correcting a bad situation so quickly!
