I was recently in a Home Depot Store located in Southern California and overheard an employee being yelled at unprofessionally by what appeared to be the employees manager or someone above this person. The altercation took place on an aisle next to the one I was on and I was able to over here the language that the person was using against the employee. I was wondering if there was someone that would be able to give me information about reporting a situation to someone that is above the person I saw doing this. After the employee was done being scolded by the Home Depot worker that was yelling at them I walked out the front of the aisle and remember the name of this person. I then consulted a cashier and asked if the person worked for the store. He informed me that "the people in orange polo shirts" were part of a special outside group that didn't work for the Home Depot Store directly but an outside source. He wasn't able to tell me too much more about their system or structure so I was wondering how I find out about reporting someone as a customer.
