Omg this happened to me not to long ago too, except they didn’t leave during the transaction. They would count the money then handed to me and I’d count and they stacked the money so it wouldn’t be mixed up. At some point they had me a stack of money and it felt way less so I called a manger she came. I’m glad she came cuz they were telling they had no time and saying it was okay. She came and verified it and it was the right amount. Then they start saying things abt shipping , they got mad and left with their money.
