Family Dollar review: policy for employee vs customer rights

On November 11, 2019 I went to the 180 Mclean location I filled my cart with 97.00 worth of merchandise got to the register and realized I forgot my wallet which was left on my dining room table. I clearly said to the cashier " I am so sorry I will be right back please hold my merchandise."
I left the store at 9:10pm arrived back to pick up my merchandise at 9:20 maybe 9:25 the latest. I said I'm back where is my stuff she blatantly said " oh I put it back". I said what, I told you I was coming right back-and I said where is the supervisor who was standing right there before and after I left . She said well people do this all the time- I said you should not put put a basis of people do this all the- there should be some type of protocol in place. Meanwhile she never looked at me she talked to me while writing very disrespectful not using any customer service skills.
Let me tell you something in order for your store to be successful you must apply good customer service. The supervisor was rude the stock was rude the cashier was rude. Nobody smiles or even tries to help you . Now I live only 6 min away. I work for the City of Yonkers for 39 years.
I also work for the Mayors office. My name is Roseanne Bannister, 34 Wolffe Street, Yonkers NY 10705. What I'd like to see is better customer service at this location. Just because I was treated very disrespectfully and my job is to help everybody in the City of Yonkers I feel I must take this complaint further. Please address this issue immediately. Thank you for your time
