Family Dollar review: disrespectful, rude and demeaning cashier

On 4/05/2019 at approximately 5:45pm, my husband Richard Vallejo went into the Family dollar store to purchase dog food. As he placed the bag on the counter, the cashier Blanca rang the item up and gave him the total. Richard gave her a $10 bill and was reaching through his pockets to get a $5 bill. As he was doing so, she told him "You need to pick up your pants, hurry up and pay and get out the store." He was completely caught off guard and immediately felt disrespected so he through the $5 on the counter and stormed out the store with no receipt. He informed me of what happened and I opted to return the item and get a refund as I knew that our hard earned money would not be spent at this location. I went back in approached Blanca and asked her for a refund, in which she rudely stated "No, you do not have a receipt. Leave the store immediately." I stayed as I wanted my money back and then opted to call the police instead as she was demeaning and disrespectful. The law enforcement officer arrived and I (Blanca Vallejo) was given a Criminal Trespassing warning and was required to sign a document stating I would never revisit that location again. This by far has been the most absurd interaction that I have ever had in my life, my husband and I have never felt this disrespected in any establishment in my 50+ years on this Earth. We work hard for our money and refuse to ever spend a dollar moving forward at any Family Dollar establishment. I will be reporting this incident via social media as I would never want anyone else to be mistreated as we have been on today. I pray that this interaction is rectified immediately as we are in shock and awe at such behavior and I now have this criminal trespassing on my record. I am a law abiding citizen and have been all my life - I ask that you have this removed immediately and reprimand / terminate the employee. There is a clear pattern of misbehavior as I see on google reviews.
