Dollar General complaint: Disappointed and startled customer

I stopped by the Dollar General in Lewiston Woodville, N.C. at approximately 5:30 P.M. on Saturday, July 9th, 2022 to purchase an anniversary card. I went to the register to pay for it. The counter has a plastic shield with a cut-out to pass small items and money through due to the recent COVID outbreak .I passed the card through the opening. As she was checking me out, I took the money out of my wallet, passed it through the opening, and put it on the counter behind the plastic. The clerk, named Lacy. stated that I had put too much money on the counter and then said hand me the money, please, in a very rude tone. I thought at that time that something was wrong with her hands. I passed her the money and saw that nothing was wrong with her hands, so I asked why did she ask me to pass her the money when it was already near her on the counter. In a nasty tone of voice, she said that it was disrespectful for me to put the money on the counter????? I thought that’s what you are suppose to do with it!!!!! I then exited the store, got to my truck, and returned to the store to look for a supervisor. I saw an older female at the rear of the store. As I approached her, I saw Lacy talking with her and heard Lacy speak the word disrespectful. I asked the female was she a manager and she said she was an assistant manager. I explained to her what happened and she too said that it was disrespectful. It really startled me. I then asked if it was a company policy and she said no. Lacy was still standing there and there was no one at the front with the cash register. I noticed that neither employee had a name tag. I then asked for the assistant manager’s name. She would not give it to me. I asked again and she would not give it to me. I then told her that I was issuing a formal complaint with the corporate office. I then walked to the front and saw three customers waiting at the register to check out. The clerk still wasn’t back at the register. I then exited the store. It was a blessing that the customers in the store were honest. I still can’t understand why I was DISRESPECTFUL.
