Subway complaint: How Rude

My husband and I walked into Subway 5699-0. There were 2 African American gentlemen in front of us. The tinier of the two immediately said to me Hey girl I do not know the gentleman so I just nodded. He started approaching me and my husband said he was gonna get a hug from me. I stood behind my husband and said no get away from me I’m contagious His friend went to the table behind us and said he needed his hooch and grabbed a white Styrofoam cup of alcohol.
We ordered our sandwiches. The sandwich maker gave us price on cookies. We got a large fountain drink, 3 cookies which he said was a dollar, foot long Philly cheese and foot long turkey.
I was still upset about that one man as I have anxiety and am leaving on a flight to NJ for my daddy real sick. The sandwich maker told me 21.62 which I knew was not right.
When I got home we ate the sandwiches which were absolutely delicious and I checked our receipt against the menu. I called the location at 8:36pm and spoke with Jay who said he was manager.
He initially stated SO I also told him that the sandwich maker verbally gave me the price on the cookies and he still seemed to be disregarding everything I said. He first said that it was tax however the receipt clearly itemized the 7 percent. I asked him to help me understand the discrepancy as my husband and I started arguing and I could not handle it. I told Jay I was leaving in the morning and did not want to argue just explain it to me so I can explain to husband. He stated it’s simple it’s on your receipt I told him I am in retail, the customer is always right even when they are not, courtesy goes a long way. I told him I was filing a complaint.
You can look on your cameras about the other customers and their actions. My husband wanted me to call an attorney friend but would not.
I am a long time customer and have never had an issue. I appalled at the treatment by the customer and manager. If my husband was not there I do not know what would have happened. Employees never intervened.
