The worst !!! The woman was the most unhelpful , rude, idiotic person I have ever come across I explained I needed a box to send clothes to hurricane relief victims ; she could not be nitjer s to put her phone down and help me find a box ; absolutely shameful this woman is an employee obviously disgruntled and disrespectful to the general public. Oct 15th 2024 8am glasses short heavy set African American woman with the worst attitude I have ever seen she needs to be moved to the back where she doesn’t have to talk to the public look for help finding a box to post !!!
